§ 35
If a termination by the landlord is deemed to be prompted by or associated with an attempt to obtain an unreasonable rent or other unreasonable rental terms, the rent tribunal may invalidate the termination's validity and determine that the tenancy can only be terminated with the tribunal's approval. The same applies if a termination, due to other special circumstances in connection with its issuance, is deemed contrary to customary good rental practice, making it considered unreasonable.
