The Cape Cod-based tribe had more than 300 acres placed into trust by the federal government last year, a decision that’s being challenged in federal court by a rival casino developer and local opponents.

The lands include 150 acres in the city of Taunton about 35 miles from downtown Boston and another 170 acres in Mashpee.
