Robin Tyler and Diane Olson, a California gay marriage poster couple, have announced they plan to divorce. 

The duo, who were one of 14 same-sex couples to challenge California's ban on gay marriage in 2008, made their announcement in the wake of a federal court's ruling Tuesday that the ban, known as Proposition 8, was unconstitutional. The ruling puts Proposition 8 on track for possible consideration by the U.S. Supreme Court.

Robin Tyler filed for divorce from Diane Olson after three years of marriage on Jan. 25, according to MSNBC:

We're human and we went through difficult times, Tyler said of their short-lived marriage. What is the standard to expect when you integrate equality? ... We're just like anybody else, and that's all they can expect of us.

The couple were married in the Beverly Hills Courthouse in June 2008, after seven straight years of attempting to do so. The wedding, which took place on the courthouse steps, made Robin Tyler and Diane Olson a poster couple for gay rights. The couple had known each other for 40 years and had been together for 18 years at the time of their marriage, according to The Daily Beast.

I don't know how to describe it -- I wanted this all my life, Olson told the Jewish Journal on their wedding day. Every time I went to a girlfriend's wedding, and when my brother got married, it was something I always wanted for myself. It looks like God must have wanted it for me, too.

Four months after the couple were wed, California voters passed the bitterly disputed Proposition 8, which banned gay marriage in the Golden State. All gay and lesbian couples who were wed before Nov. 4, 2008, could stay married, but no new gay marriages were allowed to take place under the new policy.

MSNBC reports Olson spoke out about gay rights in between the passage of Proposition 8 and the 9th U.S. Circuit Court of Appeals' ruling on Tuesday:

For a bunch of people to tell me who I can love, who I can marry, who I can say this is my person, this is who I choose to spend the rest of my life with, it's mindboggling to me that a few religious people can vote for our equal rights, she said. 

And Tyler spoke out as well, according to MSNBC, saying: Marriage is so important it's the most important relationship that you can have as an adult when you get older.
