The Supreme Court has been asked to hear a fourth case related to the Defense of Marriage Act (DOMA), the 1996 law which outlaws federal agencies from recognizing the legal marriages of gay and lesbian couples.

On Wednesday, the Massachusetts-based legal group Gay & Lesbian Advocates & Defenders (GLAD) asked the high court to review a case challenging the constitutionality of the law.

Last month, a federal district court judge in Connecticut ruled in Pederson v. Office of Personnel Management (OPM) that DOMA violates the Constitutional rights of gay and lesbian couples.

Judge Vanessa Bryant issued a 104-page ruling, which concluded that the “Court finds that no conceivable rational basis exists for the provision.”

“The provision [Section 3 of DOMA] therefore violates the equal protection principles incorporated in the Fifth Amendment to the United States Constitution.”

Lead plaintiff Joanne Pedersen, a federal retiree, was blocked from adding her wife Ann Meitzer to her health insurance.

“We aim to provide the Supreme Court all the evidence it needs to overturn DOMA finally, and quickly,” GLAD said in a statement announcing its filing.

Three of the four cases appealed to the high court have yet to be considered by federal courts of appeals.

In addition to the four DOMA cases, the Supreme Court has also been asked to review a ruling which found California's gay marriage ban, Proposition 8, to be unconstitutional.

Analysts believe the court will accept at least one of the cases when it returns from summer recess.
