The Obama administration is asking the U.S. Supreme Court to make the case of an 83-year-old New York lesbian who had to pay $363,000 in estate taxes its highest priority among the pending lawsuits challenging the Defense of Marriage Act.

In an 11-page supplemental brief filed on Friday, U.S. Solicitor General Donald Verrilli writes that the case of Windsor v. United States -- which recently led the U.S. Second Circuit Court of Appeals to conclude DOMA is unconstitutional -- should take precedence among other pending lawsuits challenging the anti-gay law.
