As City Desk noted last week, D.C. will recognize same-sex marriages performed in other jurisdictions starting 12:01 a.m. Tuesday, barring any last-ditch appeal today. That’s when the clock runs out on the 30-day congressional review of the marriage recognition bill passed in May by the D.C. Council and signed by Mayor Fenty. The Board of Elections and Ethics recently rejected an attempt led by Maryland Bishop Harry Jackson to put the bill up for a referendum, a decision upheld by Superior Court Judge Judith Retchin.

After Tuesday, same sex marriages performed in other states and countries will be legally recognized in the District. The possibility of a ballot initiative similar to California’s Proposition 8 being brought to overturn the law remains open.

“There have been legally married gay and lesbian couples in D.C. for several years, but until this moment those marriages went unrecognized by the city,” said Michael Crawford, co-chair of D.C. for Marriage, a grassroots outreach group that recently gathered 130 signatures from local clergy members in support of marriage equality. “Now these couples are able to celebrate their marriages and have them recognized as valid in the District. This is a wonderful step forward in ensuring that all families in the District are treated equally under the law.”

Assuming nothing happens to delay the implementation of the law between now and midnight, what do married same sex couples need to do to get recognized by the District? Nothing, really. If you have a valid marriage license from another jurisdiction, you are automatically legally married as far as the District is concerned. But if you or someone you know is planning any kind of second wedding celebration tonight or tomorrow, be sure to send in your photos (and invites!) to tips@dcist.com.
