In its current ruling of 2 November 2020 (2-15 O 23/10), the Regional Court of Frankfurt a. M. assumes that the state-imposed closure of a retailer in the course of the Corona pandemic does not in principle constitute a defect in the leased object or a breach of the business basis. A defect in the leased object would only exist if the reason for the state use prohibition was found in the leased object itself or its relationship to the environment. Corona-related closures of businesses are, however, linked to the type of use and the public traffic which increases the risk of infection. A breach of the business basis could also only be assumed in (existence-threatening) exceptional cases, which the court did not consider to exist in the case decided. The tenant could therefore neither demand a reduction in rent nor an adjustment of the contract.
