Se descubren larvas misteriosas
en ambos océanos de Panamá

por Sonia Tejada – STRI (in English, click here)

Estas pequeñas larvas flotan libremente en el agua salada, mientras que sus padres viven en el fondo del mar, generalmente sin ser detectados. Los estudios genéticos nos proporcionan pistas de que hay más especies por descubrir.

Las fotos de muestras de agua de mar tomadas con microscopios, revelan la etapa larval de estas poco conocidas criaturas marinas llamadas foronídeos, pero contrary a sus padres es otra historia. Aunque estas extravagantes larvas llamaron la atención de los científicos que desde el siglo XIX estudian el plancton, pequeñas plantas y animales que flotan en los océanos, hasta el momento, sólo hay unas 15 especies de foronídeos conocidos en el mundo, basados en especímenes adultos. Un estudio de las larvas, publicado esta semana por científicos del Instituto Smithsonian de Investigaciones Tropicales (STRI) en Panamá detectó ocho especies potencialmente nuevas.

“La diversidad global de animales marinos pequeños y raros como los foronídeos, está muy subestimada”, comentó Rachel Collin, científica de STRI. “No sabemos qué animales hay por ahí, y sabemos aún menos sobre cuál podría ser su papel en los océanos del mundo”.

Debido a que las larvas de foronídeos flotan en el agua de mar, a menudo son más fáciles de muestrear que los adultos, que viven en el lecho marino enterrados la arena, en sedimentos o en escombros. Y las larvas no se parecen a los adultos, lo que dificulta saber qué larva pertenece a qué adulto sin hacer una especie de prueba de paternidad: comparar las secuencias de ADN larvales con el ADN de sus posibles padres.

Llamados así en honor a la diosa egipcia Phoronis, los foronídeos, de cuerpos tubulares, anclan sus cuerpos a rocas o corales y agitan una corona de tentáculos para capturar pequeñas partículas de alimentos. Para reproducirse, producen huevos y espermatozoides. Cuando los huevos eclosionan, las larvas salen al agua y se convierten en parte del plancton.

Las larvas tienen cuerpos cilíndricos con un anillo de tentáculos en la parte superior y una gran capucha que sirve para capturar alimentos. Algunos están decorados con manchas de pigmento amarillo y en otros es posible ver manchas rojizas o rosadas de células sanguíneas a través de sus cuerpos translúcidos. Finalmente, descienden al lecho marino, se convierten en adultos y completan su ciclo de vida, considerado el ciclo más común en el reino animal.

Los científicos recolectaron plancton de la Bahía de Panamá en la costa del Pacífico y de Bocas del Toro en la costa del Caribe. Al examinar el plancton utilizando un estereomicroscopio, encontraron más de 50 larvas de foronídeos, 23 del Pacífico y 29 del Atlántico. Utilizando una técnica genética llamada código de barras, basada en la secuenciación del ADN, pudieron distinguir tres tipos de plancton de foronídeos en la Bahía de Panamá y cuatro tipos en el Caribe.

El ADN de genes particulares de cada uno de estos animales era distinto de cualquier otro registrado en GenBank, la colección global de ADN de más de 300,000 organismos, lo que significa que todos pueden ser especies nuevas para la ciencia. Sin embargo, encontrar a los adultos de estas especies puede llevar años, especialmente porque muy pocos científicos estudian foronídeos.

Editorials: Insulting constitutional process; and Enlisting for the Sunni jihad?

0
jcv / lc
Juan Carlos Varela and Laurentino Cortizo meet to talk transition. Photo from Cortizo’s Twitter feed.

Is it now Plan B, or Plan A version 2.0?

In the days after the election we found that the PRD won 33 percent of the vote, but got 35 of 71 seats in the National Assembly. Independent candidates won 20 percent of the vote, but got fives seats. Independents outpolled both the Panameñista Party and by a long shot MOLIRENA, but the Panameñistas got eight seats and MOLIRENA five. By this year’s permutation of the ways that seats are allocated from multi-member circuits, a newcomer, running on both the PRD and MOLIRENA slates, lost out to an old face, also running in the same circuit on both the PRD and MOLIRENA slates, who got many fewer votes than the newcomer did.

THEN, a week after the election, the PRD gave a copy of a 27-page constitutional reform package to a newspaper more or less aligned with the PRD – the public still doesn’t get to see a copy – and that would make ALL candidates for the legislature run in these manipulable, cockamamey multi-member circuits. We need this because? Something about less corruption, they say, plus we are warned from the banking distict that if we had a constitutional convention somebody might question the white minority apartheid regime that is the Panama Canal Authority board of directors.

Problem is, to get this thing jammed through without any public input – the business lobbies who had a hand in drafting it are not “the public” but in fact cringe in terror at the collective majority of Panamanians – the same proposal would have to pass in as special legislative session called by President Varela for that express purpose, and then by the incoming new PRD-dominated legislature. If Varela called a session for one proposal that was passed, and the new legislature passed a different version it would have to be submitted to the voters in a national referendum.

The latest noises we hear suggest that Cortizo will submit constitutional questions to the voters early in his administration. As in, Varela seems not to be going along with the plan.

The changes mentioned are inane, would make everyone run for legislature in larger circuits where it costs more to run. Of course the rich love that, plus the added feature that with the larger circuits all of the legislature could come from upscale neighborhoods and none from where the poor live.

The parts of the proposal of which we have been told would create a runoff system with three new sets of calculation – first round percentage for the front runner, then whether the second place person came within five percent, then who has the most votes in the end – instead of the present one comparison. And hasn’t Panama seen elections wherein it was declared that in some district or circuit or mesa there were irregularities, so that part of the result will be tossed out for the final count? It’s how Noriega’s man was declared the winner in 1984. Add the extra calculations and there would be more opportunity for this sort of thing. Why not just if nobody gets 50 percent plus one, there is a runoff between the top two finishers? Might it be that parties that never get much more than one-third of the vote are afraid of that?

We ought to have a constitutional convention. The same guarantee that the nation would have if Varela won’t cooperate and Cortizo sends something to the voters would apply if a convention does a poor job of drafting a new design for how we govern ourselves. In either of those cases, then people just vote the proposal down. That has also happened before.

Off to the jihad, dragging Panama along?

Donald Trump has sent an aircraft carrier group and a large supply of missiles to the Middle East.

En route the usual Sunni jihadis, the Saudis and the Emiraitis, have told the world how Iran has blown holes in four tankers in Emiraiti waters. Showing zero evidence they blamed Iran. But satellite photos show no damage, no leakage.

Those photos from on high having been published, now the Saudis say that an explosives-laden drone has attacked one of their pipelines. Did it happen? If it did and the attack came from Yemen it served them right. Maybe a regime the cuts a journalist apart alive with a bone saw has a different version of Islamic law that maintains that they can bomb and starve a civilian population but it’s vile terrorism if anyone shoots back at them.

The world doesn’t buy it. The folks who were on the same side of the table with the United States to negotiate the Iran nuclear deal – having been insulted and called enemies by Trump, and having their domestic politics disrupted by Trump-backed neofascists – say that they will not join the USA in this adventure.

So does America sign on for an expansion of the Sunni jihad, which after having failed in Syria and Iraq is now setting its sights on Iran? Getting involved in a Middle Eastern religious war would be the worse sort of perversion of the founders’ foreign policy principles, but that would be just one more perversion for Trump to sample.

The question is whether Panama will see the need to go along. With Juan Carlos Varela one might expect that. With Nito Cortizo it’s not so clear.

Panama should maintain cordial relations with Iran, stay out of any war in the Middle East, and maintain the neutral right of passage for the ships of all nations that do not attack us. There is no reason for Panama to go down into an improvised foxhole with Cadet Bonespurs.

Sanders, Intolerant authoritarians are a global problem

A GLOBAL problem

by Bernie Sanders

One of the great crises facing the global community today is that democracy, the right of ordinary people to control their own lives, is on the defensive while authoritarianism is growing stronger.

And at its root is the fact that a handful of incredibly wealthy people are exerting enormous economic and political power over the planet. Unbelievably, in the global economy today, the top 1 percent owns more wealth than the bottom 99 percent, and a handful of billionaires own more than the bottom half of people around the world — that’s 3.7 billion people.

That is the reality.

People in our own country, and around the world, are angry and betrayed, and they feel that nobody is listening to their pain.

And one of the results of that reality is that in Europe, in Russia, in the Middle East, in Asia and elsewhere we are seeing movements led by demagogues who exploit people’s fears, prejudices and grievances to achieve and hold on to power.

Next week, Donald Trump is set to welcome one of those leaders into the White House: Hungary’s far-right authoritarian Prime Minister, Viktor Orbán.

Now, I have always found it very strange that Trump has such a hard time getting along with leaders of the world’s major democracies but feels very comfortable with authoritarians like Orbán, Putin, Xi Jinping, Bolsonaro and Mohammad bin Salman.

But the truth is, while they all differ in some respects, they share a number of key attributes: hostility toward democratic norms, antagonism toward a free press, intolerance toward ethnic and religious minorities, and a belief that government should benefit their own selfish financial interests.

This trend certainly did not begin with Trump, but there’s no question that authoritarian leaders around the world have drawn inspiration from the fact that the leader of the world’s oldest and most powerful democracy seems to delight in shattering democratic norms.

Other authoritarian states are much farther along this kleptocratic process.

In Russia, it is impossible to tell where the decisions of government end and the interests of Vladimir Putin and his circle of oligarchs begin. They operate as one unit. Similarly, in Saudi Arabia, there is no debate about separation because the natural resources of the state, valued at trillions of dollars, belong to the Saudi royal family. In Hungary, far-right authoritarian leader Viktor Orbán is openly allied with Putin in Russia. In China, an inner circle led by Xi Jinping has steadily consolidated power, clamping down on domestic political freedom while it aggressively promotes a version of authoritarian capitalism abroad.

So the question is: Where do we go from here?

To effectively oppose right-wing authoritarianism, we cannot simply go back to the failed status quo of the last several decades. In order to fight this trend, we need to strengthen the global coalition of progressive democrats.

While authoritarians promote division and hatred, we promote unity, inclusion, and an agenda based on economic, social, racial, and environmental justice.

The people of the world must come together to end the absurdity of rich and multinational corporations stashing over $21 trillion in offshore bank accounts to avoid paying their fair share of taxes and then demanding that their respective governments impose an austerity agenda on their working families.

It is not acceptable that the fossil fuel industry continues to make huge profits while their carbon emissions destroy the planet for our children and grandchildren.

It is not acceptable that a handful of multinational media giants, owned by a small number of billionaires, largely control the flow of information on the planet.

It is not acceptable that trade policies that benefit large multinational corporations and encourage a race to the bottom hurt working people throughout the world as they are written out of public view.

It is not acceptable that, with the Cold War long behind us, countries around the world spend over $1 trillion a year on weapons of destruction, while millions of children die of easily treatable diseases.

In order to effectively combat the rise of the international authoritarian axis, we need a global progressive movement that mobilizes behind a vision of shared prosperity, security and dignity for all people and that addresses the massive inequality that exists, not only in wealth but in political power as well.

Such a movement must be willing to think creatively and boldly about the world that we would like to see.

We must take the opportunity to reconceptualize a genuinely progressive global community based on human solidarity, that recognizes that every person on this planet shares a common humanity, that we all want our children to grow up healthy, to have a good education, have decent jobs, drink clean water, breathe clean air, and live in peace.

Our job is to reach out to those in every corner of the world who share these values and who are fighting for a better world.

In a time of exploding wealth and technology, we have the potential to create a decent life for all people. Our job is to build on our common humanity and do everything that we can to oppose all of the forces, whether unaccountable government power or unaccountable corporate power, who try to divide us up and set us against each other.

We know that those forces work together across borders. We must do the same.

This species has three distinct ranges that do not overlap. One runs from Honduras though Panama and into Peru. There are separate zones in Paraguay and in northeastern Argentina and southern Brazil. Here they are found mainly in humid lowland forests, either old growth or mature second growth. They are on both sides of the isthmus but more common on the Atlantic Side. They don’t go to altitudes much higher than 3,000 feet. Primarily insectivorous, they are also known to eat fruit.

Esta especie tiene tres rangos distintos que no se superponen. Uno corre desde Honduras a través de Panamá hacía Perú. Hay dos otras zonas separadas, una en Paraguay y la otra en el noreste de Argentina y el sur de Brasil. Aquí se encuentran principalmente en bosques húmedos de tierras bajas, ya sea de crecimiento antiguo o de crecimiento secundario maduro. Están a ambos lados del istmo pero más comunes en el lado Atlántico. No llegan a altitudes mucho más altas que 3,000 pies. Principalmente insectívoros, también se sabe que comen frutas.

nps
The first Americans also came on foot, by this route. US National Parks Service graphic.

Mr. President:

You were elected to govern the United States of America. Not to divide it by race, religion, or national origin or ethnicity. The first Americans, who founded this country, weren’t born on this country. They, like your ancestors, where born not in the US but overseas. Please remember, is the “United” States of America.

All Americans, wealthy or poor, must have opportunities to live on decent conditions. You must seek not party members benefits, but benefits for all Americans regardless of their political affiliation or belief. The press is not your enemy, it is a mean for all Americans to learn about your conduct and decisions, which impacts all Americans. It has been said that the Roman Empire fell because there was no press.

You were elected not to play golf and send tweets, but to govern and guide this great country. To what we all expect will be a better future. Not to alienate the countries that have supported America, in policies and wars. That damage will be difficult to overcome.

The credibility of our country and our policies will be hard to restore. Your presidency will eventually pass, but America and the need for credibility and respect for it from other nations will remain. Make true your frequent images embracing the American flag.

“Make America Great Again,” your campaign slogan, must not be a hollow statement, but a true assertion. Time will judge you, and time is a merciless judge.

La contaminación química del plástico

La contaminación química del plástico, una amenaza silenciosa

por Ethel Eljarrat, Instituto de Diagnóstico Ambiental y Estudios del Agua (IDAEA – CSIC)

Cada año se producen un total de 300 millones de toneladas de plástico. De ellas, se estima que ocho millones acaban directamente en los mares y océanos de nuestro planeta.

La inundación de plásticos de mares y océanos es uno de los principales problemas ambientales del planeta, según el informe del Programa de las Naciones Unidas para el Medio Ambiente (PNUMA) publicado este 2019. De no tomarse medidas, existe un elevado riesgo de deterioro de los ecosistemas marinos y, por consiguiente, de la biodiversidad marina.

El impacto físico de las basuras plásticas en la fauna es evidente. Es frecuente encontrar animales, como las tortugas, que han quedado enganchados con redes o cuerdas, quedando estrangulados en sus extremidades y sufriendo falta de riego sanguíneo.

Además, muchas especies marinas han incorporado plásticos en su organismo, incluyendo cetáceos, aves, tortugas, peces y plancton. Muchos mueren por la ingestión de plástico que les ha bloqueado el sistema digestivo. Se calcula que más del 60 % de todas las especies de aves marinas tienen rastros de plásticos en sus intestinos y se han encontrado plásticos en los estómagos de casi 700 especies de vertebrados marinos. Sin embargo, el impacto químico de los plásticos es menos evidente.

Los aditivos de los plásticos

Los plásticos están formados por polímeros, normalmente derivados del petróleo, a los que se añaden diversos compuestos químicos, que pueden constituir más del 50 % del peso del plástico. Cada compuesto químico que se añade tiene su función:

  • Los plastificantes proporcionan la flexibilidad, dureza o rigidez, dependiendo de las diferentes aplicaciones del producto.

  • Los estabilizantes se añaden para inhibir o retardar el mecanismo de oxidación y degradación de los polímeros durante su fabricación.

  • Los retardantes de llama se añaden a todo tipo de material para evitar su flamabilidad. Así, si se produce un incendio, la propagación de las llamas es más lenta.

  • Los filtros solares se añaden para absorber la luz UV y así aumentar la vida útil de los plásticos expuestos al sol.

  • Los antibacteriales se añaden para evitar que bacterias crezcan en el plástico. Esto es muy importante para el destinado a usos alimenticios.

Existen más de 3 000 sustancias químicas diferentes asociadas a los plásticos y más de 60 caracterizadas como sustancias de alto riesgo para la salud, siendo algunas de ellas persistentes, bioacumulables y tóxicas. Existen cientos de estudios científicos que demuestran que aditivos comunes del plástico, como los bisfenoles, los ftalatos, los retardantes de llama y los metales pesados, son muy peligrosos para la salud.

Los microplásticos

Los microplásticos son pequeños pedazos de plástico que miden menos de medio centímetro, como el tamaño de un grano de arroz. Llegan al mar por dos vías diferentes:

  • Por un lado, proceden de los microplásticos fabricados específicamente para ser usados en artículos como cosméticos, pasta de dientes, jabón de manos y productos de limpieza. Cada año, los fabricantes europeos utilizan 3 125 toneladas de microplásticos. Las aguas residuales y las escorrentías los llevan a las vías fluviales y de aquí van a parar a los mares.

  • Por otro lado, cuando los plásticos llegan al mar, se van fragmentando en pedazos mucho más pequeños por la acción de la luz solar y el oleaje.

Además, los microplásticos tienen la capacidad de atraer y acumular las sustancias tóxicas presentes en el medio marino, de manera que funcionan como un medio de transporte de contaminantes. Así, estos fragmentos de plástico, con todas las sustancias químicas asociadas a ellos, así como con todos los contaminantes del medio atraídos sobre ellas, son ingeridos por la fauna marina, desde los peces más pequeños hasta los mamíferos.

La amenaza de la contaminación química

Una vez ingeridos los microplásticos, el animal acumula los compuestos químicos asociados en sus tejidos. Estos compuestos químicos no se metabolizan, por lo que se van acumulando en el animal a lo largo de toda su vida.

Además, se produce el efecto de la biomagnificación: los niveles de estos compuestos van aumentando a medida que se asciende en la cadena trófica, de forma que las presas tienen menor concentración de sustancias tóxicas que el predador. De esta manera, los mayores niveles de contaminación los vamos a encontrar en las especies de nivel trófico superior, como los delfines.

Los compuestos químicos asociados a los plásticos, como los mencionados anteriormente, no provocan toxicidades agudas, o sea, no producen efectos adversos inmediatos. Sin embargo, sí que producen una toxicidad crónica, es decir, provocan los efectos adversos como resultado de pequeñas dosis diarias de una sustancia química.

Algunos son disruptores endocrinos: imitan el comportamiento de las hormonas e incluso concentraciones pequeñísimas pueden producir mutaciones graves a nivel celular. Algunas de las alteraciones que se han relacionado con los aditivos tóxicos del plástico son diversos tipos de cáncer, infertilidad, problemas de desarrollo, enfermedades neurodegenerativas, enfermedades cardiovasculares, obesidad y diabetes.

Repercusión en la salud humana

Los humanos, al estar en la cúspide de la pirámide trófica, no estamos exentos de peligro. Las vías de exposición humana a los aditivos químicos de los plásticos son básicamente dos: la ingesta y la inhalación.

El mayor aporte corresponde a la dieta. Cuando ingerimos un pescado, estamos incorporando a nuestro organismo todos los contaminantes que ha acumulado a lo largo de su vida. Es importante destacar que el problema no viene por el plástico que el animal tenga en el tracto gastrointestinal, ya que esta parte no es comestible. El problema viene de los aditivos químicos del plástico, que sí se acumulan en los tejidos grasos, como el músculo, una parte que sí es comestible.

También hay que tener en cuenta que los alimentos pueden contaminarse durante la producción, el procesamiento industrial (empaquetado, enlatado y secado) y el almacenamiento, debido a la presencia de contaminantes en algunos materiales utilizados en el procesamiento, así como a la transferencia de contaminantes desde los materiales de envasado.

La otra vía de exposición humana es a través del aire. Estos químicos se hallan en las partículas del aire que respiramos, sobre todo en interiores (casas, oficinas, …), ya que dichos ambientes están llenos de materiales plásticos. Normalmente, esta exposición es inferior a la de la dieta, ya que solemos comer hasta 2 kg de alimentos por día, mientras que la inhalación de partículas a través de la respiración suele ser de 20 mg por día.

Así pues, la contaminación por plástico supone un grave problema ambiental y una potencial amenaza para la salud humana, por lo que son necesarias medidas para intentar reducir el uso de material plástico en la sociedad.

What to look for from Nito Cortizo: Constitutional changes

0

This is one of the main groups spearheading the demand for passage of a set of constitutional changes that they have not had the courtesy to publish. Photo from Mr. Cortizo’s Facebook page.

He says that he wants what the business groups want, whatever it is. Can he get it?

by Eric Jackson

How did we get here?

Panama lives under the dictatorship’s constitution. The old Guardia Nacional stepped in on October 11, 1968, to overthrow President Arnulfo Arias — again. This time the precipitating event was that the president who was sworn in that October 1 announced that he would be altering the order of promotions for the combined military and police forces. Arias was notorious racist and back in the 40s and 50s his nemesis José A. Remón broke down the racial and class entry barriers to the officer corps, such that by 1968 a darker cast of characters has risen to its penultimate heights. More than anything it was a job action, but the troops did away with a constitutional order that had upheld a “government of cousins” that few who were not related missed. 

The coup came at a sensitive time, when talks about the future of the Canal Zone and the Panama Canal were underway. Something approaching a final deal was almost at hand, but when the old order was discarded that was put on hold as well. It was not until a few years later when the two coup leaders, Omar Torrijos and Boris Martínez, had a falling out that was decided in the formers’ favor via more than anything else the intervention of the intelligence (G2) chief, on Manuel Antonio Noriega. With Martínez exiled to the USA Torrijos had to figure out a strategy to deal with the Americans.

The old order’s election cycle became a time constraint. For the consumption of the US public and politicians, some democratic institutions needed to be built or rebuilt to show off abroad. Not that the general staff was about to give up real power, of course, but there was a need for some fig leaf of of legitimacy. So the representantes — more or less city council members with more executive and distributive functions than their counterparts in most other countries — were convened for a 1972 constitutional convention. What emerged was a military regime with elected local officials and an elected legislature, but with those politicians who played along given resources to distribute among their constituencies. There would be legal political parties, which were given the power to remove those elected on their tickets if they sold out and didn’t toe the party line. Men in uniform appointed the civilians of the executive branch.

It was good enough to get a 1977 agreement with the United States. Then, in 1981, General Torrijos died in a plane crash.

WHAT? Caudillos don’t live forever? Succession had not been contemplated. So in 1983 the first patch was applied, wherein there would be a direct popular election of the president. That was held in 1984, and stolen from Arnulfo Arias by General Noriega. The military still held the power and, after the death of Noriega’s mentor and older brother in 1985, was used and abused ever more erratically. That Uncle Sam was demanding over Panamanian support in the Contra War against Nicaragua complicated things.

There came the Noriega crisis, with crippling US economic sanctions, a 1989 election that the military could not win and thus tried to annul, then increasing hostilities leading up to the 1989 US invasion that ended the dictatorship. The 1972 constitution was kept, but patched four more times.

So what is it now? Multiple corruption scandals in the judicial, legislative and executive branches. High public debt and pervasive public institutional dysfunction. An economy that looks good by fudged figures but not to working people, in which the canal and the banking sector may be doing well enough but in which agriculture and industry are hardly producing anything. With almost all legislators stealing from the public treasury and the courts an international embarrassment, time for what? Another constitutional patch.

CoNEP
CoNEP contemplates constitutional changes. From a CoNEP photo.

This time around…

Two of the country’s main business groups, the National Private Enterprise Council (CoNEP, mostly big business with which the government will directly deal), and the CCIAP, began to formulate constitutional changes about a year ago. This they did in consultation with the United Nations Development Program (UNDP). 

You might think of peacekeepers, the World Health Organization or UNICEF feeding hungry children when you think of the UN. However, the UNDP is the point organization for neoliberal policies in the less rich countries. In Panama their advice has included privatizing public pension programs, cutting instruction in civics, history and the arts in the public schools and cutbacks in public health care programs.

Last August and September, CoNEP and the CCIAP began to describe what they were thinking about in terms of constitutional changes. One matter was the way that the Supreme Court is selected and organized. They were for raising the minimum age to become a magistrate from 35 to 45, extending the terms from 10 to 20 years, and instead of presidential appointments creating a nine-member panel representing “civil society” to come up with a vetted pool of potential appointees, who would have to be approved by a two-thirds vote of the legislature. Were the president’s choice to be rejected the sitting magistrates would appoint a temporary jurist while the politicians couldn’t make up their minds?

Civil society? In Panamanian reality, that means rich white people not holding any public post at the moment. As it was described last year, representatives of business organizations, organized labor, non-governmental organizations, civic clubs, academia, the nation’s main bar association (the Colegio de Abogados) and people designated by the president.

WHICH businesspeople?  Certainly not those of the 40% of Panama’s work force who are in the informal economy. Certainly not the Chinese-Panamanian merchants who vastly outnumber the members of CoNEP and the CCIAP combined. And you can reasonably estimate which sorts of clubs and non-governmental organizations the business groups have in mind.

There were also proposals floated about changing the way the legislature is selected and operated. Suggestions of a bicameral legislature with nationally elected senators were made, and others of at-large deputies taking seats in a National Assembly of reduced size. There was not any talk about getting rid of the anomalous multi-member circuits and the odd results that come from that, but lots of talk about fewer legislators in all, as if fewer politicians means less corrupt government.

In the middle of last December when nobody was paying much attention due to the holidays, we were told of a unified CCIAP – CoNEP constitutional proposal, to be passed by way of a vote by the present legislature and then by the new one in keeping with Article 313 of the Political Constitution of Panama. The proposal was submitted to the government. But neither the government nor the CCIAP nor CoNEP has ever published the thing for any citizen to see. Nor have any of the media who were told about this proposal published it.

Varela objects. President Varela ran for office in 2014 by promising a constitutional convention, but then said that he couldn’t control the outcome so reneged. In response to the business groups’ plan, he proposed to add another item to the May 5 ballot, a referendum on whether a constitutional convention should be called. CoNEP and the CCIAP said that it was too late in the game, that no distraction from their undisclosed document should be allowed.

And the National Assembly, which has been feuding with the president, killed his proposal. And did this and that and complained how horrible and illegal it was for the Comptroller General to say that they stole. And let the last regular session of this legislature end on April 30, without any action on the CoNEP – CCIAP proposal.

Can’t let THEM in on constitutional reform! Some don’t even know the banking district. Electoral Tribunal photo.

For Cortizo, the math is the easier part now

In the recent election campaign, the number one and number two finishers in the presidential race both said that they supported both the business groups’ proposal and the preferred method of passing it. That could still be an arithmetic problem if enough of the deputies who didn’t run for re-election or who ran and lost don’t attend and don’t send their suplentes in their stead. No matter what Rómulo Roux said, some of the CD caucus might still be indisposed to help Nito Cortizo get anything that he wants. But there have historically been ways to persuade disgruntled lame duck legislators.

The problem for Nito and the business lobbies is in the person of Juan Carlos Varela and in the provisions of Article 149 of the constitution. 

The current legislature’s regular sessions are over. They can only act in a special session. And Article 149 says that only the president calls a special session, sets the time and place and specifies the subject matter. The National Assembly can’t take up any business that’s not on the president’s call.

Lawyers might argue. They might say that Article 313 provides that the legislature may start a constitutional process of their own volition, without the president’s or anybody else’s permission. Most probably, though, that would have had to have been in the regular sessions.

But what if Varela convenes them to ratify some contract and they do that, adding constitutional reform as an amendment? It’s probably not proper for a bunch of reasons, but nobody really knows what our politicized and dysfunctional Supreme Court might say. 

Most probably Cortizo has an electorate of one to convince if he wants to advance the scheme — Juan Carlos Varela.

But anyway, WHAT IF constitutional reform comes as an amendment to some other business?

Then surely the text of what the next legislature passes wouldn’t be exactly the same. It’s OK for the new legislature to vary the wording of the previous set of deputies.  But in that case Section 2 of Article 313 provides that any constitutional amendment passed in that way has to be ratified by the voters in a national referendum to be held within six months.

Would Cortizo want to risk the wrath of an electorate that thinks that a fast one was being pulled on them at such an early point in his term? The critics are already lined up.

Most probably a Cortizo presidency does not see any constitutional reform until much later, either in light of an acute crisis or as business to finish as the term is ending. 

A roughly translated tweet by noteworthy television pundit Alvaro Alvarado: “There are sectors pushing this very dubious assembly to carry out reforms to the constitution. This would be totally irresponsible. These men have no right to undertake a national project such as this.”
