This decision affirms a $2.7 million judgment in favor of two tenants against new landlords that harassed the tenants and then wrongfully evicted them in a fake owner move-in all in violation of San Francisco’s rent control ordinance. The ordinance provides for treble damages for violations like these, but the trial court properly exercised its discretion to reduce the trebled damages by $800,000 to avoid an unconstitutional penalty. The landlords’ many arguments were either forfeited by inadequate objections in the trial court or inadequate briefing on appeal, or were meritless. Evidence of the landlords’ similar abuse of tenants in other buildings was admissible to show bad faith as a basis for trebling damages. Jury instructions were proper. The landlords’ competing instructions were not.
