The group formed to challenge the constitutionality of Proposition 8, California's gay marriage ban, released a video looking back on the case as the Supreme Court prepares to issue a ruling.

The American Foundation for Equal Rights' (AFER) case against the 2008 voter-approved constitutional amendment was filed in 2009. It broke ground for being the first to challenge such a ban in federal court.

Opponents of gay nuptials, led by the National Organization for Marriage (NOM), proposed a constitutional amendment after the California Supreme Court struck down the state's laws limiting marriage to heterosexual couples. Passage of Proposition 8 came after more than 18,000 gay and lesbian couples had exchanged vows in California.

The Supreme Court could hand down a ruling in Hollingsworth v. Perry, and a second related case, as early as Monday. The court is expected to rule by June 27.

In a 5-minute video released Friday, AFER traces the case from its start to the steps of the Supreme Court. As the video nears its end, David Boies, lawyer for the plaintiffs, is seen telling reporters, “It's now in the hands of the Supreme Court.” (The video is embedded on this page.
