Mexico lamented Texas' execution of a Mexican national and called it a clear contravention of a 2004 world court decision that found U.S. authorities had violated international law by failing to inform foreign suspects of their right to consular assistance.

"Mexican Edgar Tamayo Arias was executed today in Texas," Mexico's Foreign Relations Secretariat said Wednesday night, shortly after Texas authorities confirmed that the convicted cop killer had been put to death.

The announcement mentioned the efforts made by the Mexican government to have the case reconsidered by Texas judicial authorities "in light of the lack of consular notification" when Tamayo was arrested.

In March 2004, the International Court of Justice ruled in the Avena and Other Mexican Nationals case that U.S. authorities should review the death sentences of 51 Mexicans.

The ICJ found that the Mexican convicts were denied the guarantee under international law to be informed of their right to consular assistance to mount a defense in court.

That right is enshrined in Article 36 of the Vienna Convention, a treated signed by Washington and ratified by the U.S. Senate.

"The government of Mexico issues a call that effective action be taken and that (authorities) avoid the carrying out of other sentences ignoring the Avena ruling, which harm the regime of consular assistance and protection agreed to between the countries," the Mexican government said Wednesday.

Texas insists it is not bound by the ICJ decision and U.S. federal lawmakers have yet to pass proposed legislation that would bring the country into full compliance with the world court ruling. EFE
