(Reuters) - Some U.S. business interests intend to signal support for gay marriage by signing on to two briefs due to be filed this week with the Supreme Court, according to lawyers involved in the process who argue that gay rights are good for business.
Various companies are set to join separate friend-of-the-court briefs, one expected on Wednesday in a case challenging the federal Defense of Marriage Act and one due on Thursday in a case that questions a California law that banned gay marriage.
Major companies are to urge the court to invalidate Proposition 8, the California law in question, and strike down Section 3 of the federal Defense of Marriage Act, which defines marriage as between one man and one woman.
The brief to be filed in the Proposition 8 case, a draft of which was obtained by Reuters, has been joined by such companies as Apple Inc, Nike Inc, Facebook Inc, Morgan Stanley, Intel Corp, Xerox Corp, AIG Inc and Cisco Systems Inc.
