ALBANY – During a term with a decided commercial tilt, the state Court of Appeals will consider whether a controversial restaurant proposal for Union Square Park violates the public trust doctrine, a principle the court introduced in 2001 to help determine when municipal parkland may be used for private purposes.

As it hears arguments in 30 cases beginning today, the court also will be asked to clarify language commonly included in insurance contracts on replacement costs for damaged buildings and to settle a dispute that arose in lower courts in Manhattan over the admissibility of scientific evidence in residential mold exposure cases.
