Petitioner, Municipality of San Joaquin, seeks the reversal of a decision of the Court of First Instance of Ilo­ilo dismissing the former's petition for prohibition, contest­ing the legality of Executive Order No. 436 of the President of the Philippines, dated July 10, 1961, creating the muni­cipality of Lawigan out of twenty-one (21) barrios theretofore forming part of said municipality of San Joaquin.  Respondents-appellees are the persons appointed by the President as mayor, vice-mayor and councilors of Lawigan, who are sought to be re­strained from performing their functions as such, upon the ground that Section 68 of the Revised Administrative Code, on which said Executive Order is based, constitutes an undue de­legation of legislative powers, and, hence, unconstitutional.  The lower court, however, held otherwise.  Hence, this appeal.

The issue herein has been squarely taken up and set­tled in Pelaez vs. Auditor General, G. R. No. L-23825, promul­gated on December 24, 1965, which upheld the theory of appel­lant herein, and rejected the view taken in the appealed deci­sion.

WHEREFORE, said decision is hereby reversed, and an­other one shall be entered declaring the aforementioned Executive Order No. 436 null and void ab initio, and directing here­in respondents-appellees to refrain from acting as officers of the municipality of Lawigan, with costs against them.

IT IS SO ORDERED.
