The government of Puerto Rico acting through its legislature, may create a public corporate authority or authorities and may authorize such authority or authorities or any other public corporate authority or any municipal corporation or political subdivision, acting directly or through any officer or agency thereof or through a public corporate authority, to undertake slum clearance and urban redevelopment projects and urban renewal projects and to do all things, exercise any and all powers, and to assume and fulfill any and all obligations, duties, responsibilities, and requirements, including but not limited to those relating to planning and zoning, necessary or desirable for receiving Federal assistance under title I of the Housing Act of 1949 (Public Law 171, Eighty-first Congress), as amended [42 U.S.C. 1450 et seq.], or any other law, except that public corporate authorities (as distinct from municipalities or political subdivisions) created or authorized to operate in accordance with this Act, as amended, shall not be given any power of taxation or any power to pledge the full faith and credit of the people of the Territory, or municipality, or political subdivision, as the case may be, for any loan whatever. The Legislature of Puerto Rico may, with respect to any public corporate authority or authorities empowered or which may be empowered to undertake slum clearance and urban redevelopment projects and urban renewal projects, provide for the appointment and terms of office of the members thereof, and for the powers of such authorities, including authority to accept whatever benefits the Federal Government may make available for slum clearance and urban redevelopment projects and urban renewal projects, and authority, notwithstanding any other Federal law, to borrow money and to issue notes, bonds, and other obligations of such character and maturity, with such security, and in such manner as the respective legislatures may provide. Such notes, bonds, and other obligations shall not be a debt of the United States, or of any Territory or municipal corporation or other political subdivision or agency thereof other than the public corporate authority which issued such notes, bonds, or obligations, nor constitute a debt, indebtedness, or the borrowing of money within the meaning of any limitation or restriction on the issuance of notes, bonds, or other obligations contained in any laws of the United States applicable to Puerto Rico, or to any municipal corporation or other political subdivision or agency thereof.
