Article 115. For their internal government, the States shall adopt the popular, representative, republican form of government, with the free Municipality as the basis of their territorial division and political and administrative organization, in accordance with the following principles:

None of the above-mentioned officials, when holding office as incumbents, may be elected for the term immediately following as alternates, but persons designated as alternates may be elected for the term immediately following as incumbents, unless they have performed such duties during the preceding term.
2. Municipalities shall freely administer their finances, which shall be composed of the taxes imposed by the legislatures of the States, and which, in all cases, shall be sufficient to meet the municipal needs.
3. Municipalities shall be invested with juridical personality for all legal purposes.

The federal Executive and the governors of the States shall command the public forces in the municipalities where they customarily or temporarily reside.

Governors of the States may not hold office for more than six years.

Governors of the States who hold office by regular or special election may not, in any case or for any reason, again occupy that office in an interim, provisional or substitute character, or be in charge of that office in any capacity.

The following may never be reelected for the immediately following term:
  1. A substitute constitutional governor or a governor designated to complete a term in case of the permanent absence of the constitutional governor, even when he has a different official title.
  2. An interim or provisional governor or a citizen who, under any title, replaces the governor during temporary absences, provided he held the office during the last two years of the term.
The constitutional governor of a State must be a Mexican citizen by birth and a native of the State or with actual residence therein for not less than five years immediately preceding the day of the election.

The number of representatives in the state legislatures shall be proportional to the inhabitants of each State; but in no case shall there be fewer than seven deputies in States having a population of less than 4000, 000 inhabitants; or nine in those in which the population exceeds that number but does not reach 800, 000; and eleven in States having a population greater than the latter figure.
Deputies to the legislatures of the States may not be reelected for the term immediately following.

7.
