A. A tenant may refuse to pay any increase in rent which is in violation of the provisions of this chapter, and such violation shall be a defense in any action brought to recover the possession of an apartment unit or to collect rent.
B. In addition to the remedies set forth in subsection A of this section, in any action brought to recover the possession of an apartment unit, the court may consider as grounds for denial any violation of any provision of this chapter. In addition, a court determination that the action was brought in retaliation for the exercise of any right conferred by this chapter shall also be grounds for denial. (1962 Code § 11-7.04)
