Lawyer Ulrich Busch told The Associated Press late Thursday he is asking for the German government to retract its agreement to take Demjanjuk on humanitarian grounds.

He says it might take two weeks for the appeal filed with a Berlin administrative court to be ruled upon. And he says even if the ruling is in Demjanjuk's favor, American authorities still could deport him.

Demjanjuk (dem-YAHN'-yuk) is wanted in Germany on an arrest warrant accusing him of being an accessory to 29,000 murders at the Nazis' Sobibor death camp in occupied Poland. He denies the charges.

Melisa Keeton and Shelley Wolfe of Des Moines received their waiver by 9 a.m.

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 case from New Haven, Conn., pits white firefighters, who showed up at the court Wednesday in their dress uniforms, against the city over its decision to scrap a promotion exam because no African-Americans and only two Hispanic firefighters were likely to be made lieutenants or captains based on the results.

As is often the case with closely fought social issues at the court, Justice Anthony Kennedy appeared to hold the key to the outcome. He seemed concerned that New Haven scuttled the test without determining that there were flaws that might have led to the racially disproportionate results.

"So shouldn't there be some standard that there has to be a significant, a strong showing after the test has been taken that it's deficient? Before it can be set aside?" he said.

Kennedy often frowns on racial classifications, yet he is not as opposed to drawing distinctions on the basis of race as his more conservative colleagues.

But where Kennedy saw shades of gray, the rest of the court seemed to view the case clearly in terms of black and white.
