(a) 
The enumeration of particular powers in this charter is not exclusive. The city shall have and may exercise all powers which it would be competent for this charter specifically to delegate, except as clearly prohibited or limited in this charter.
(b) 
The city is empowered to use all methods and do all things it deems necessary or convenient to carry out the powers in this section within the limits of the law.
All ordinances of the city not inconsistent with the provisions of this charter, shall remain in full force and effect until altered or repealed by the city council; provided, that the power to pass such ordinances under former charters has not been repealed expressly or implied by the terms of this act.
All ordinances of the city published in book or pamphlet form and purporting to be published “By authority of the City Council of the City of Robstown,” shall be received by all the courts of the State of Texas as prima facie evidence of the due passage and publication of such ordinances as appear therein; provided, that no person shall be precluded from showing by competent evidence, that any ordinance published “By authority of the City Council of the City of Robstown,” as aforesaid, is not a true copy of the original ordinance.
It shall not be necessary in any action, suit or proceeding in which the city is a party for any bond, undertaking or security to be demanded or executed by or on behalf of said city in any of the state courts, but all such actions, suits, appeals or proceedings shall be conducted in the same manner as if such bond, undertaking or security had been given as required by law, and said city shall be just as liable as if security or bond had been duly executed.
The property, real and personal, belonging to the city shall not be liable to be sold or appropriated under any writ of execution, nor shall the funds belonging to the city in the hands of any persons be liable to garnishment.
Before the city shall be liable for damages for personal injuries of any kind the person injured or someone in that person’s behalf shall file with the city secretary in the manner prescribed by ordinance notice in writing of such injury within one hundred eighty days after the same has been sustained, reasonably describing the injury claimed and the time, manner and place of the injury. The failure to so notify the city within the time and manner specified herein shall exonerate, excuse and exempt the city from any liability whatsoever.
Acts of the city council previously enacted in granting franchises, assessing and collecting taxes, and the disbursement of same, the enforcement of its ordinances by criminal proceedings or otherwise, the collection of fines and the disbursement of same and any and all enforcement of the penal laws of this state, are hereby in all things validated and made as valid and binding as if passed by a legal city council.
This charter shall not be construed as a mere grant of enumerated powers, but shall be construed as a general grant of power and as a limitation of power on the government of the city in the same manner as the Constitution of Texas is construed as a limitation on the powers of the legislature. Except where expressly prohibited by this charter, each and every power under Article XI, Section 5 of the Constitution of Texas, which it would be competent for the people of the city to expressly grant to the city, shall be construed to be granted to the city by this charter.
This charter shall be deemed a public act, may be read in evidence without pleading or proof, and judicial notice shall be taken thereof in all courts and places.
If any section or part of a section of this charter is held to be invalid or unconstitutional by a court of competent jurisdiction, the same shall not invalidate or impair the validity, force or effect of any other section or part of a section of this charter.
The council shall have the power, by ordinance, to renumber and rearrange all articles, sections and paragraphs of this charter or any amendments thereto, as it shall deem appropriate, and upon the passage of any such ordinance a copy thereof, certified by the city secretary, shall be forwarded to the secretary of state for filing.
