§ 158. Real property of authorities exempt from levy. All real property of an authority shall be exempt from levy and sale by virtue of an execution, and no execution or other judicial process shall issue against the same, nor shall any judgment against an authority be a charge or lien upon its real property; provided, however, that the provisions of this section shall not apply to or limit the right of obligees to foreclose or otherwise enforce any mortgage of an authority or the right of obligees to pursue any remedies for the enforcement of any covenant of an authority or of any pledge or lien given by an authority on its rents, fees or revenues.
