If any such general-law city, town, or village has heretofore been established by incorporation or attempted incorporation more than 5,280 feet gulfward beyond the coastline, the corporate existence of such general-law city, town, or village is in all things validated, ratified, approved, and confirmed.
The boundaries of such general-law city, town, or village, including the gulfward boundaries to the extent of 5,280 feet gulfward beyond the coastline, are in all things validated, ratified, approved, and confirmed and shall not be held invalid by reason of the inclusion of more territory than is expressly authorized in Article 971, Revised Civil Statutes of Texas, 1925, as amended, or by reason of the inclusion of territory other than that which is intended to be used for strictly town or city purposes as required by Section 7.002, Local Government Code or by reason of not constituting a city, town, or village.
Neither this Act nor the general laws nor the special laws of the state shall have the effect of validating, ratifying, approving, or confirming the inclusion of territory in any such general-law city, town, or village more than 5,280 feet gulfward beyond the coastline.
If for any reason it should be determined by any court of competent jurisdiction that any such general-law city, town, or village has heretofore been incorporated in violation of the laws of the state in effect as of the date of such incorporation or is invalid, the corporate boundaries of any such general-law city, town, or village shall be revised and reformed to exclude all territory more than 5,280 feet gulfward of the coastline.
