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.

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.

John Prisque of Bethlehem, Pa., was sentenced to a 70-month term for convictions of obstructing the investigation into Atlantic States Cast Iron Pipe Co. in Phillipsburg and violating clean water and air regulations. Four others also face sentencing.

In one of the most serious instances, an employee was killed after being crushed by a forklift that prosecutors say had faulty brakes.

Atlantic States is a division of McWane Inc., based in Birmingham, Ala.

The court's 5-4 decision puts new limits on the ability of police to search a vehicle immediately after the arrest of a suspect.

Justice John Paul Stevens said in the majority opinion that warrantless searches still may be conducted if a car's passenger compartment is within reach of a suspect who has been removed from the vehicle or there is reason to believe evidence of a crime will be found.

"When these justifications are absent, a search of an arrestee's vehicle will be unreasonable unless police obtain a warrant," Stevens said.

Justice Samuel Alito, in dissent, complained that the decision upsets police practice that has developed since the court first authorized warrantless searches immediately following an arrest.

"There are cases in which it is unclear whether an arrestee could retrieve a weapon or evidence," Alito said.

Even more confusing, he said, is asking police to determine whether the vehicle contains evidence of a crime. "What this rule permits in a variety of situations is entirely unclear," Alito said.

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.

"I love you all. May the Lord be with you. Peace. I'm done," Michael Rosales said in his brief, final statement.

Three of his brothers were among the witnesses at the injection. No friends or relatives of his victim were present.

Rosales was pronounced dead at 6:17 p.m., eight minutes after the lethal drugs began to flow.

Rosales, 35, confessed to the 1997 slaying of Mary Felder a day after her body was found by her grandson, who routinely checked on her. Rosales told police he was high on cocaine and looking for money when he broke into her home as she slept. She was attacked when she woke up.

Rosales was the 13th Texas prisoner executed this year in the nation's most active capital punishment state.

About 90 minutes before Rosales was scheduled to be taken to the death chamber, the U.S. Supreme Court rejected appeals to delay the lethal injection so Rosales could have more time to assemble a state clemency petition and press claims he may be mentally retarded and therefore ineligible for execution.

Prosecutors argued that deadlines for clemency petitions had passed and that the mental retardation issue already had been reviewed and rejected by the appeals courts, including a federal appeals court which in 2004 had stopped Rosales' then-scheduled execution.

Felder, a grandmotherly presence in the neighborhood where she was known lovingly as "Miss Mary," was pummeled and stabbed with a two-pronged fork and a steak knife. Records show she had 113 wounds, including some from needle-nose pliers.
