Electronic Arts has joined a coalition of American businesses opposing the Defense of Marriage Act, a federal law that defines marriage as a union between a man and a woman. The game publisher said in a statement Wednesday that it was joining dozens of business in signing an amicus brief that urges the 9th U.S. Circuit Court of Appeals to find the 1996 law unconstitutional. In part, the statement reads: DOMA presents a number of problems for businesses like EA, as it creates regulatory, tax, and discrimination complications for employers, and that's why we're standing against it. The underlying lawsuit impacts all employers no matter how big or small, and no matter the industry, and we encourage other business to join these efforts.
