A popular vote shall further be resorted to on a measure initiated by the People if one-tenth of the qualified voters so petition. A fully elaborated bill must accompany such petition. The National Cabinet shall lay the bill together with a statement of its attitude before the National Assembly. The popular vote does not take place if the desired bill is enacted without amendment by the National Assembly. A popular vote may be taken on the budget, tax laws, and laws relating to the classification and payment of public officers only by authority of the National President. The procedure in connection with the popular referendum and initiative will be regulated by national law. ARTICLE 74 The National Council has the right to object to laws passed by the National Assembly. The objection must be filed with the National Cabinet within two weeks after the final vote in the National Assembly and must be supported by reasons within two more weeks at the latest. In case of objection, the law is returned to the National Assembly for reconsideration. If an agreement between the National Assembly and the National Council is not reached, the National President may within three months refer the subject of the dispute to the People. If the President makes no use of this right, the law does not go into effect. If the National Assembly disapproves by a two-thirds majority the objection of the National Council, the President shall promulgate the law in the form enacted by the National Assembly within three months or refer it to the People. ARTICLE 75 An act of the National Assembly may be annulled by a popular vote, only if a majority of those qualified take part in the vote. ARTICLE 76 The Constitution may be amended by process of legislation. But acts of the National Assembly relating to the amendment of the Constitution are effective only if two-thirds of the legal membership are present, and at least two-thirds of those present give their assent. Acts of the National Council relating to the amendment of the Constitution also require a two-thirds majority of all the votes cast. If an amendment to the Constitution is to be adopted by the People by popular initiative, the assent of a majority of the qualified voters is required. If the National Assembly adopts an amendment to the Constitution against the objection of the National Council, the President may not promulgate this law, if the National Council within two weeks demands a popular vote. ARTICLE 77 The National Cabinet issues the general administrative regulations necessary for the execution of the national laws so far as the laws do not otherwise provide. It must secure the assent of the National Council if the execution of the national laws is assigned to the State authorities. _SECTION VI_
