Over 200 businesses will try to convince the Supreme Court on Wednesday to deny a federal law defining marriage as a heterosexual union, according to NBC News. The companies, including Microsoft Corp, Google Inc, Starbucks Corp and others, will have their lawyers file briefs in the DOMA case. In one such brief filed today, an attorney said the legislation does not create any uniformity within the U.S. because 12 states allow same-sex marriage or recognize same-sex unions from other states, creating a burden for employers, particularly those who do business nationwide. Separately, lawyers from another group of employers have stated that they planned to file a brief on Thursday in a case questioning the California law that bans gay marriage. The two cases are to be will be debated before the Supreme Court on March 26 and 27.
