Tenancy to be in abeyance during usufructuary mortgage in favour of tenant.

If any land is mortgaged by a landlord by way of a usufructuary mortgage to a tenant cultivating such land, the tenancy of such land shall be in abeyance during the period the mortgage subsists. After the expiry of the said period it shall, notwithstanding any other law for time being in force, be lawful to the tenant to continue to hold the land on the terms and conditions on which he held it before the mortgage was created.
