WASHINGTON (AP) — The Supreme Court begins its new term on Monday with an argument that spotlights police actions based on a mistaken understanding of the law.

A case from North Carolina turns on an officer's decision to pull over a car because one brake light was not working, even though state law requires only one to operate a car legally. The stop led to a search and the discovery of cocaine.

The justices are beginning their fifth year together, and Chief Justice John Roberts is starting his 10th year on the bench.

Their term could be one for the ages if they decide, as seems likely, to take on the issue of same-sex marriage and settle once and for all whether gay and lesbian couples have a constitutional right to marry.
