Jerome and Walker v. DC Rental Housing Commission [PDF], 682 A.2nd 178 (1996) - Rental Housing Act effectively merges the notice to cure and the notice to quit into one required notice before landlord may file suit for possession based on tenant’s failure to cure violation of tenancy.

Allen v. DC Rental Housing Commission [PDF], 538 A.2nd 752 (1988) – Finding that tenant received notice of proposed rent increase was not supported by substantial evidence so that challenged rent increase was invalid; landlord testified only that she sent former employee a notice to be delivered to tenant and that former employee customarily served notice on tenants on the day he received them.
