Facts: The Municipality of Sinacaban was created by EO 258 of then Pres. Quirino pursuant to Sec. 68 of the Revised Admin. Code.Sinacaban laid claim to several barrios based on the technical description in EO 258. The Municipality of Jimenez asserted jurisdiction based on an agreement with Sinacaban which was approved by the Provincial Board of Misamis Occidental which fixed the common boundary of Sinacaban and Jimenez.
The Provincial Board declared the disputed area to be part of Sinacaban. It held that the earlier resolution approving the agreement between the municipalities was void since the Board had no power to alter the boundaries of Sinacaban as fixed in EO 258. Jimenez argued that the power to create municipalities is essentially legislative (as held in Pelaez v Auditor General), then Sinacaban, which was created thru and EO, had no legal personality and no right to assert a territorial claim.

In the case of Municipality of San Narciso v Mendez, the SC laid the factors to consider in validating the creation of a municipal corporation:
1. The fact that for 30 years, the validity of the corporation has not been challenged;
2. The fact that no quo warranto suit was filed to question the validity of the EO creating the municipality; and
3. The fact that the municipality was later classified as a 5th class municipality, organized as part of a municipal circuit court and considered part of a legislative district in the Constitution apportioning the seats in the House.
In this case, the following factors are present:
1. Sinacaban has been in existence for 16 years when Pelaez was decided in 1965 and yet the validity of EO 258 creating it had never been questioned.
2. It was only 40 years later that its
