Same-sex couples in Iowa began applying for marriage license Monday after a state Supreme Court ruling legalizing gay unions took effect.

The high court issued an order early in the day confirming that the appeals process in the case has officially concluded.

The Iowa Supreme Court's unanimous and emphatic decision on April 3 made Iowa the third state to allow same-sex marriage, joining Massachusetts and Connecticut. Vermont has passed a law that will take effect in September.

U.S. District Judge Christina A. Snyder ruled the so-called widow penalty doesn't necessarily require that immigrants' permanent residency applications be denied when their American spouses die. Citing a 2006 decision by the 9th U.S. Circuit Court of Appeals, Snyder ruled this week that applicants don't lose their status as spouses of U.S. citizens if the death occurs before the government rules on their applications.

The decision, if made final, would be a victory for more than 200 people across the country who have been affected by the widow penalty, said attorney Brent Renison, who filed the class-action lawsuit in Los Angeles.

"This case is very significant because it's the first that follows the circuit court decision and gives guidance to the agency on what it can and cannot do in these situations," Renison told The Associated Press on Tuesday.

The U.S. Citizenship and Immigration Service has argued the law requires that residency applications be rejected for immigrants whose American spouses die within two years of being married.

The high court agreed to hear a U.S. Justice Department appeal defending the 1999 animal cruelty law after it was struck down for infringing free-speech protections.

A U.S. appeals court declared the law unconstitutional and overturned the conviction of a Virginia man, Robert Stevens, who sold three videos of pit bulls fighting each other and attacking hogs and wild boars.

His conviction in 2005 was the first in the country under the law. Stevens had been sentenced to 37 months in prison.

By a 10-3 vote, the appeals court rejected the government's argument that, for the first time in more than 25 years, there was a new category of speech not covered by constitutional free-speech protections. Usually, videos and other depictions are protected as free speech, even if they show abhorrent conduct.
