(4) An initiative request may consist of a general proposal or take the form of a complete draft.
(5) If such a request consists of a general proposal and if it meets with the approval of the Federal Chambers, the latter shall prepare a partial revision along the lines of the proposal and submit their draft to the people and the Cantons for adoption or rejection. If the Federal Chambers do not approve of the request, the question of partial revision shall be submitted to the decision of the people; if the majority of the Swiss citizens casting a vote decide in the affirmative, the Federal Assembly shall undertake the revision in conformity with the decision of the people.
