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

Euro Disneyland Rides: Walt Disney Imagineering, the creative arm of the Walt Disney Co., filed a breach of contract suit against Sequoia Creative Inc. over vehicles and lap bars for three rides at Euro Disneyland. The Los Angeles Superior Court suit says Sequoia agreed in March, 1989, to design the equipment but did not finish on time and delivered substandard goods. The suit seeks more than $540,000 because Disney allegedly had to complete the work itself. (Filed June 25, 1990. Case No. BC004278)
