A married lesbian couple on Monday asked a federal judge to rule in a case challenging Pennsylvania's law that prohibits the state from recognizing the legal marriages of gay couples.

Isabelle Barker and Cara Palladino married in Massachusetts in 2005 before moving to Philadelphia later that same year when Barker got a job at Bryn Mawr College. The couple is raising a young son.

“We took on the commitment of marriage in 2005 and have supported each other through life's ups and downs,” said Palladino. “We think it is wrong for Pennsylvania to void our marriage and treat us as though we are unmarried when we are very much a loving family.”

The couple filed for summary judgment in the case known as Cara Palladino and Isabelle Barker v. Governor Thomas Corbett and Attorney General Kathleen Kane.

Plaintiffs are asking for the state to recognize the out-of-state legal marriages of gay couples. The lawsuit does not seek to require Pennsylvania to allow gay couples to marry.

Gay nuptials are legal in the neighboring states of New York, New Jersey, Delaware and Maryland.
