Venezuela's Supreme Court said there would be no recount of the razor-thin presidential election victory Sunday by Hugo Chávez's heir, Nicolás Maduro.

Opposition activists and independent observers called the judge's declaration blatant and legally unfounded favoritism from a purportedly independent body that is packed with confederates of President-elect Maduro, Chávez's hand-picked successor.

The recount issue wasn't brought before the court, but its president, Luisa Morales, appeared on television to declare that the opposition call for an examination of each and every paper vote receipt had "angered many Venezuelans."

It was an unsubtle reminder that virtually every lever of power in Venezuela sits in the hands of a ruling party unafraid to use almost all means at its disposal to marginalize its opponents.

"In Venezuela the system is absolutely automatic, in such a way that manual recounts don't exist," Morales said.

Opposition candidate Henrique Capriles later told a TV interviewer that Morales should be disqualified from legal decision on petition that his campaign filed Wednesday for a recount.

A day earlier, Capriles canceled a march in the capital planned for Wednesday, saying the government planned to react with violence. 

Maduro hectored the opposition during a 45-minute live appearance on state television Wednesday, calling his opponents "fascists" plotting to overthrow the government.

"Superman could not win an election here," Diego Arria, a former U.N. ambassador and conservative member of the opposition coalition, said resignedly.

"We're left with the option of calling the United Nations, the Organization of American States and the Inter-American Human Rights Commission, but that won't have any impact here," Arria told The Associated Press. "If the population stands down, we lose."

The National Electoral Council on Monday ratified Maduro as the winner of the previous day's vote with 50.8 percent to Capriles' 49 percent.

The United States, meanwhile, appeared to soften its insistence on a recount as U.S. Secretary of State John Kerry left open the possibility of recognizing Maduro as president even if the votes aren't reviewed.

In South America, several presidents will hold an emergency meeting on Thursday evening in Lima, where a Unasur regional summit is taking place, to discuss the political crisis in Venezuela.

Peruvian government officials did not say if the meeting was being held as a show of support for Maduro, or whether regional leaders wanted to issue a collective call for calm in Venezuela.

The governments of Brazil, Peru, Ecuador, Colombia, Bolivia and Argentina, among others, have recognized Maduro's victory.

Most of the Unasur leaders, including President Dilma Rousseff of regional heavyweight Brazil, will then head to Venezuela for the swearing-in ceremony.

Maduro's government said 15 countries had confirmed they were sending high-level delegations, among them Bolivia, Ecuador, Nicaragua, Iran, China, Saudi Arabia, Qatar, Haiti, Uruguay and Argentina.

Kerry said there was no plan to send a U.S. diplomat but when asked about whether the U.S. would recognize Maduro as legitimate, he said, "I can't give you a yes-or-no answer on that."

"If there are huge irregularities, we're going to have serious questions about the viability of that government. But that evaluation has to be made, and I haven't made it yet," Kerry told the House Foreign Affairs Committee.

Maduro boomed angrily in a later TV appearance.

"Take your eyes off Venezuela, John Kerry! Get out of here! Enough interventionism!"

Capriles has presented a series of allegations of vote fraud and other irregularities that he contends easily add up to more than Maduro's 262,000-vote winning margin out of about 14.9 million votes cast. In addition, the electoral council says about 100,000 votes from abroad had not been counted by Wednesday, and Capriles got about 90 percent of such overseas ballots in the October presidential election won by Chávez.

The list of alleged problems includes:

— Government backers forced pro-Capriles observers out of 283 polling places at which 722,983 votes were cast, and the lack of witnesses raises the possibility of fraud, including double voting.

— Menacing bands of government supporters turned pro-Capriles voters away from the polls.

— There were 3,535 damaged voting machines, representing 189,982 votes.

— Voting rolls included 600,000 dead people.

Morales, the Supreme Court chief, said Venezuela's voting system is so automated that a manual count doesn't exist. Technically, however, a recount is possible as paper receipts are issued for every vote cast and can be checked against tallies done by each voting machine, voter registries and centralized records.

The non-partisan Academy of Political and Social Sciences at the Central University of Venezuela said paper ballots are explicitly described in Venezuela's election law as a tool for investigating vote irregularities. "Recounting votes, along with protests and peaceful demonstrations, is one of the legitimate means of democratic co-existence," it said.

Maduro and his ruling circle have accused Capriles of inciting postelection violence by "neo-Nazi gangs" that the government said claimed eight lives and injured 61.
