Celebrities and Los Angeles officials have called for a boycott against hotels owned by the Sultan of Brunei, where a harsh law that makes gay sex punishable by death went into effect on Wednesday.

The nine hotels are some of the most exclusive in the world and make up the Dorchester Collection, owned by the Brunei Investment Agency, an arm of the government. They include two where Hollywood moguls dine and entertainment glitterati are feted during awards season: the Beverly Hills Hotel and Hotel Bel-Air in Los Angeles. Others include the Dorchester in London and the Hôtel Plaza Athénée in Paris.

The new penal code in Brunei, a small monarchy on the island of Borneo in Southeast Asia, is based on the most extreme interpretation of Shariah, an Islamic law based on the Quran and other writings. The law calls for death by stoning not only for sex between men but also for adultery. The penalty for theft is the amputation of limbs.

“Every single time we stay at or take meetings at or dine at any of these nine hotels we are putting money directly into the pockets of men who choose to stone and whip to death their own citizens for being gay or accused of adultery,” George Clooney wrote in a column last week on the website Deadline.
