A day after a group of prominent Republicans joined a Supreme Court battle over gay marriage, dozens of major American corporations, including Facebook, Apple, and Intel, announced they would also side with the pro-equality forces in court. Sixty companies have signed on to their own amicus brief, to be filed in the case over California's Proposition 8, arguing that laws banning same-sex marriage "send an unmistakable signal that same-sex couples are in some way inferior ... a proposition that is anathema to amici's commitment to equality and fair treatment to all." At least 75 current and former Republican officials are planning to file a similar brief in the case, which will be argued before the Supreme Court next month.

According to Fortune, the new brief has the backing of some of the biggest names in the corporate world including AIG, Cisco, Levi Strauss, Nike, Office Depot, Oracle, Panasonic, and Xerox. (They're people too!) In addition to the simple issues of fairness and equality, the brief also argues that same-sex marriage bans are just plain bad for business. 

Proposition 8 impedes businesses from achieving the market's ideal of efficient operations—particularly in recruiting, hiring, and retaining talented people who are in the best position to operate at their highest capacity.

In other words, no one is going to move from Massachusetts to Silicon Valley for a job if they can't bring their spouse and family with them. And don't forget the wedding industrial-complex: "Increased wedding celebrations can mean additional revenue for many businesses." Just one more argument aimed at the conservative side of the bench in the hopes they'll wipe out this law for good.
