Key legal question
Whether the tenant's extraordinary termination of the lease was valid or could be challenged by the landlords
Extracted holding
The landlords' opposition to the termination was abusive and therefore not protected; the termination remained effective.
Extracted reasoning
The tenant's behavior before and after termination, including withholding a leased dental microscope and cutting electricity and water, made continued performance of the lease incompatible with the landlords' insistence on continuation.
