A federal appeals court on Thursday struck down a novel and controversial California law that allowed descendants of 1.5 million Armenians who perished in Turkey nearly a century ago to file claims against life insurance companies accused of reneging on policies.

The move came when a specially convened 11-judge panel of the 9th Circuit Court of Appeals unanimously tossed out a class action lawsuit filed against Munich Re after two of its subsidiaries refused to pay claims.

The ruling, written by Judge Susan Graber, said the California law trampled on U.S. foreign policy — the exclusive jurisdiction of the federal government.

The California Legislature labeled the Armenian deaths as genocide, a term the Turkish government vehemently argued was wrongly applied during a time of civil unrest in the country.

The court noted the issue is so fraught with politics that President Obama studiously avoided using the word genocide during a commemorative speech in April 2010 noting the Armenian deaths.

The tortured legal saga began in 2000 when the California Legislature passed a law enabling Armenian heirs to file claims with insurance companies for policies sold around the turn of the 20th century. It gave the heirs until 2010 to file lawsuits over unpaid insurance benefits.
