Among the cases to be decided are ones involving politically charged movies, strip searches of students and the rights of prisoners who say DNA will prove their innocence. But the two cases likely to get the most attention concern civil rights and the proper role of race in the law. Conservative justices have favored removing race as a factor in the law, even if it means repealing part of the historic Voting Rights Act. Liberals say protections against discrimination must be preserved in law to ensure fair elections and equality in the workplace. Now in his fourth term, Chief Justice John G. Roberts Jr. has moved to scale back the civil rights laws that give special protection to minorities. If he has a majority to pull back on voting rights and job discrimination, it will provide a powerful end to the court term -- and an opening salvo in the Senate's confirmation battle over Judge Sonia Sotomayor. The outcome in these cases, like so many others, probably depends on Justice Anthony M. Kennedy. In all, 14 cases remain to be decided, with the next round of decisions expected Thursday. Here are some of the key pending questions: Voting Rights Did Congress unfairly punish the South in 2006 when it extended part of the Voting Rights Act for another 25 years? Section 5 of the voting rights law requires most states and municipalities in the South to 'pre-clear' with Washington any changes in their electoral systems. Those challenging the law say this 1960s-era rule is outdated. The court could avoid a broad ruling by saying the Austin, Texas, water district that appealed the issue is exempt from federal oversight under the existing law because it had no history of discrimination. (Northwest Austin Municipal Utility District v. Holder) Civil Rights and Job Tests When the city of New Haven, Conn., abandoned a promotional test for firefighters, did white firefighters who had earned top scores become victims of racial discrimination? Or was the city justified in dropping the test because the law frowns on tests that have a 'disparate impact' on minorities? The decision will get extra attention because Judge Sonia Sotomayor, now a nominee to the Supreme Court, joined a three-judge ruling in a lower court upholding the city's action. (Ricci v. DeStefano) Schools and Searches Were the rights of a 13-year old girl violated by school officials who ordered her to be strip-searched when they thought she might be hiding an extra-strength ibuprofen pill? The Fourth Amendment forbids 'unreasonable searches' by the government. But in April, most justices sounded wary of limiting the authority of school employees. (Safford Unified School District v. Redding) Disabled Students and Private Schools Must school districts reimburse the parents of a child with a disability who, acting on their own, enroll him in a private school? School officials complain of the high cost of these private school programs. Parents say the schools have a legal duty to offer a 'free, appropriate' education to a disabled child. (Forest Grove v. TA) Politics and the Movies Can the government regulate a corporate-funded, politically charged film if it is advertised or broadcast during an election year? Or is the movie protected by the free-speech guarantee of the First Amendment? This case involves 'Hillary: the Movie,' a documentary on DVD funded by a conservative group that had expected that Hillary Rodham Clinton would emerge last year as the Democratic presidential nominee. (Citizens United v. Federal Election Commission) Prisoners and DNA Do prisoners who say they are not guilty have a constitutional right to DNA testing of crime samples that are in custody of the police? Most states have allowed such testing, but a few, including Alaska, have refused. (District Attorney v. Osborne)
