A judge ruled Friday that Chicago-based Cook County doesn't have to wait until June to begin allowing same-sex couples to marry.

"There is no reason to delay further when no opposition has been presented to this court and committed gay and lesbian couples have already suffered from the denial of their fundamental right to marry,” U.S. District Judge Sharon Coleman ruled.

The ruling comes after same-sex couples filed a class-action lawsuit seeking to begin same-sex marriage earlier than the June date set by the state legislature. The state's gay marriage law is set to take effect June 1.

The Cook County Clerk did not fight the lawsuit and actually came out in support of it.

The decision is the latest in a long line of pro-gay marriage decisions from the courts. The number of states and jurisdictions who allow same-sex couples to marry has grown quickly over the past year.

Chicago Mayor Rahm Emanuel (D) praised the ruling on his Twitter feed.
