PER CURIAM.
This is an original proceeding by mandamus to compel the Attorney General to certify the validity of an issue of City of Killeen Waterworks and Sewer System Junior Lien Revenue Bonds. The Attorney General raises the lack of necessary parties in that holders of the first lien revenue bonds are not parties. The questions raised involve the power and the right of the city to issue Junior Lien Revenue Bonds and these in turn involve the question of whether or not Junior Lien Bonds would impair contractual provisions of the first issue. The case of City of Houston v. Allred, 123 Tex. 35, 66 S.W.2d 655, determines that the holders of the first bonds are necessary parties to the adjudication of these questions. Therefore without passing upon the merits of the other questions raised, the petition for mandamus will be dismissed unless holders of the first issue (or a sufficient number of them to represent their class) are made parties.
The clerk will issue the proper notice.
