A summary of Southern California-related business litigation developments during the past week.

Hot Tub Death: Purex Corp. and Purex Pool Products were sued in Los Angeles Superior Court by the family of an Indiana man who died in his hot tub when a thermostat allegedly failed and heated the water to 130 degrees. The breach of contract suit filed by Lois Jean Bonjour and her three children claims Purex Pool Products, which made the tub’s heater--but not the thermostat--and others backed out of a 1987 agreement to settle the suit. The case asks for more than $25,000 plus punitive damages. (Filed April 16, 1990. Case No. C758507)
