On August 8, 2012, the California Supreme Court issued a one-sentence order denying a petition to review (and ultimately overturn) a trial court decision that certified a large class action against an apartment complex owner. The decision was a setback for WLF, which filed a brief urging that the petition be granted. The suit was filed by a small number of tenants who claim that the value of their rental units was diminished by the significant amount of construction work that took place in the vicinity of their apartments. The trial court then certified them as representatives of a class of more than 1300 current and former tenants. WLF argued that the plaintiffs failed to demonstrate that the case could manageably be tried as a class action. WLF asserted that the plaintiffs failed to demonstrate that common issues of fact predominate over individual issues – an absolute prerequisite for certification of a class action.
