The contracts and agreements to be binding and valid shall likewise stipulate and provide that the observance and fulfillment thereof may be enforced and insisted upon by any third persons or parties or public officers or the officers of incorporated municipalities, associations, or public or private corporations, to be designated therein, or either or any of them, by suit or legal action instituted in any court of competent civil jurisdiction, setting forth the breach or violation of the contract, and for the enjoining thereof either by prohibitory or mandatory injunctions or both.  There shall be no costs of court or sheriff’s fees imposed in such matters, should the presiding judge of the court in which same is brought, certify that such suit confers some benefit to the history and public welfare of the State.  Such actions may be likewise brought by the principals to the contracts, for the same purposes, or by either or any of them, with the same exemption as to costs.
