A mass tort is a civil action involving numerous plaintiffs against one or a few corporate defendants. The tort may involve, for example, personal injuries suffered by numerous plaintiffs as a result of a defective product, or a mass disaster in which there were many injured persons, such as an airplane crash, or exposure of a large group of people to toxic chemicals or pharmaceuticals.
Chestnut Hill is a suburban village located six miles (10 km) west of downtown Boston, Massachusetts, United States. Like all Massachusetts villages, Chestnut Hill is not an incorporated municipal entity, but unlike most of them, it encompasses parts of three separate municipalities, each of which is in a different county: the town of Brookline in Norfolk County; the city of Boston in Suffolk County (parts of its neighborhoods of Brighton and West Roxbury), and the city of Newton, Massachusetts in Middlesex County (all of its village of Chestnut Hill). Chestnut Hill's borders are roughly defined by the Chestnut Hill, MA 02467 ZIP Code. Chestnut Hill is not strictly a topographical designation; the name refers to a series of small hills that overlook the 135-acre (546,000 m²) Chestnut Hill Reservoir rather than one particular hill. Chestnut Hill is perhaps best known as the home of Boston College.
