Highlights of actions taken Thursday by the Supreme Court. The justices:

_Made it easier for workers to show they were victims of retaliation after they accuse their employers of discrimination, ruling 9-0 in favor of a woman railroad forklift operator.

_Ruled 7-2 that defendants, not prosecutors, have the burden of proving in federal trials that they committed a crime under duress. The ruling could prompt states to change their laws.

_Ruled 6-3 that a California inmate had to go through a prison grievance system before bringing a suit claiming he was wrongly punished for alleged inappropriate activity with volunteer priests.

_Upheld, by an 8-1 vote, the deportation of a Mexican man who lived in the United States for 20 years and claimed he should not be subject to 1996 restrictions on immigrants.

_Voted 5-3 to dismiss a case involving a test for diagnosing B vitamin deficiencies. That avoided a ruling that could have affected claims over tens of thousands of older patents.
