the tenant shall be presumed to have knowledge of such activities unless the presumption is rebutted by a preponderance of the evidence. The initial hearing on the landlord's action for immediate possession of the premises shall be held within 15 calendar days from the date of service on the tenant; however, the court shall order an earlier hearing when emergency conditions are alleged to exist upon the premises that constitute an immediate threat to the health or safety of the other tenants. After the initial hearing, if the matter is scheduled for a subsequent hearing or for a contested trial, the court, to the extent practicable, shall order that the matter be given priority on the court's docket. Such subsequent hearing or contested trial shall be heard no later than 30 calendar days from the date of service on the tenant. During the interim period between the date of the initial hearing and the date of any subsequent hearing or contested trial, the court may afford any further remedy or relief as is necessary to protect the interests of parties to the proceeding or the interests of any other tenant residing on the premises. Failure by the court to hold either of the hearings within the time limits set out in this section shall not be a basis for dismissal of the case.
