53. No person may, without the authorization of the administrator, exact from a new lessee or from a sublessee a rent higher than the lowest rent that was in force during the twelve months preceding the beginning of the lease or the sublease, computed on a monthly basis. However, the highest rent during such twelve months may be exacted if it was fixed by the administrator.
Every person who pays a rent exacted in contravention to the first paragraph may within sixty days from the date of beginning of the lease or the sublease, apply for the reduction of his rent to the level provided for by the said paragraph. The administrator shall then fix the rent as if it were an application for the fixing of rent provided for in section 24.
