Here are brief summaries of the Supreme Court rulings

5 to 4: Ruled that Americans have a right to own guns for self-defense and hunting.

7 to 2: Ruled that federal judges can impose shorter sentences than those prescribed under federal sentencing guidelines for crimes related to crack cocaine, making those sentences more equal to those for crimes involving powdered cocaine.

6 to 3: Said states can require would-be voters to produce photo identification without violating their constitutional rights.

6 to 3: Found that President Bush overstepped his authority when he ordered a Texas court to reopen the case of a Mexican national on death row for rape and murder.

Unanimous: Sided with individual 401(k) retirement account holders, allowing them to sue under the Employee Retirement Income Security Act to recover losses.

5 to 3: Slashed the punitive damages Exxon Mobil must pay victims of the nation's worst oil spill. The justices cut the $2.5 billion punitive damages award in the 1989 Exxon Valdez disaster to $500 million, saying punitive damages may not exceed what the company already paid to compensate victims for economic losses.
