Administration allies in Congress pushing for a Constituent Assembly may have smuggled into the House legislative agenda a proposal that would shortcut proceedings for amending the 1987 Constitution, a congressman disclosed Tuesday.

Quezon Rep. Erin Tanada made the disclosure even as the House Committee on Constitutional Revision started tackling Tuesday nine bills seeking to convene a Constitutional Convention (Con-con) after the 2010 national elections.

Tanada, author of one of the Con-con measures, said that these appeared to have more supporters in the House than the constituent assembly (Con-ass) proposal.

But the Con-Ass proposal may have the advantage over the Con-con measures as supporters have succeeded in putting on the calendar a Charter change bill for plenary deliberation.

Tanada was referring to House Resolution 737 which had been endorsed by the Constitutional revision committee for approval on second reading.

Authored by Speaker Prospero Nograles, HR 737 proposes amendments to the economic provisions of the Constitution.

Its approval or rejection will undergo the normal proceedings for legislation in the House.

Tanada said that since House rules allow changes to any legislative proposal set for plenary approval, amendments may also be introduced to HR 737.
