TITLE EIGHT. Constitutional Reforms
Article 135
This Constitution may be subject to amendments. The vote of two-thirds of the present members of the Congress of the Union is required to make amendments or additions to the Constitution. Once the Congress agrees on the amendments or additions, these must be approved by the majority of state legislatures.
The Congress of the Union or the Permanent Committee, as appropriate, shall count the votes of the legislatures and shall announce those additions or amendments that have been approved.
