Madrid lawyer, Gonzalo Boye, said the role of the six officials in approving illegal interrogation techniques and redefining torture is well-documented.

The newspaper notes that, if issued, arrest warrants would be more of symbolic than practical significance. Indeed, the warrants are unlikely to lead to actual arrests if the officials in question stay in the United States.

The complaint, filed to the prosecutor’s office, is based on the Geneva Conventions and the 1984 Convention Against Torture, to which Spain and the US are parties, along with 143 other countries. Signatories to the convention have the authority to investigate torture cases, especially when their citizens are concerned.

That is exactly why Spain can claim jurisdiction – five citizens and residents of the country have been allegedly tortured at the infamous prison.

It should be noted that prosecutions and convictions under the Torture Convention have been rare. The New York Times quotes Reed Brody, a lawyer at the Human Rights Watch, who mentions numerous obstacles, including “a lack of political will, the problem of gathering evidence in a foreign country, and the failure of countries to pass the necessary laws.”

The paper concludes that the United States is likely to ignore a possible extradition request from Spain, because so far the Obama administration has not responded to calls from the Justice Department to launch a criminal case against John Yoo and others.
