A same-sex couple who moved to Pennsylvania after being wed in Massachusetts has asked a court to force their new home state to recognize the marriage.
Cara Palladino and Isabelle Barker lived in Massachusetts when they got married in 2005.
They later moved to the Philadelphia area to work at Bryn Mawr College.
Thirty-seven states, including Pennsylvania, do not recognize gay marriages performed legally in other jurisdictions.
