But the most serious objections to the optional form arise in connection with the petitioning. Easy though it be for a rich and strong party to bear the expense of printing, mailing, and distributing petitions and circulars, in case of opposition from the poorer classes the cost may prove an insurmountable obstacle. Especially is it difficult to get up a petition after several successive appeals coming close together, the constant agitation growing tiresome as well as financially burdensome. Hence, measures have sometimes become law simply because the people have not had time to recover from the prolonged agitation in connection with preceding propositions. Besides, each measure submitted to the optional Referendum brings with it two separate waves of popular discussion--one on the petition and one on the subsequent vote. On this point ex-President Numa Droz has said: "The agitation which takes place while collecting the necessary signatures, nearly always attended with strong feeling, diverts the mind from the object of the law, perverts in advance public opinion, and, not permitting later the calm discussion of the measure proposed, establishes an almost irresistible current toward rejection." Finally, a fact as notorious in Switzerland as vote-buying in America, a large number of citizens who are hostile to a proposed law may fear to record an adverse opinion by signing a Referendum list. Their signatures may be seen and the unveiling of their sentiments imperil their means of livelihood. Zurich furnishes the example of the cantons having the obligatory Referendum. There the law provides: 1. That all laws, decrees, and changes in the constitution must be submitted to the people. 2. That all decisions of the Grand Council on existing law must be voted on. 3. That the Grand Council may submit decisions which it itself proposes to make, and that, besides the voting on the whole law, the Council may ask a vote on a special point. The Grand Council cannot put in force provisionally any law or decree. The propositions must be sent to the voters at least thirty days before voting. The regular referendary ballotings take place twice a year, spring and autumn, but in urgent cases the Grand Council may call for a special election. The law in this canton assists the lawmakers--the voters--in their task; when a citizen is casting his own vote he may also deposit that of one or two relatives and friends, upon presenting their electoral card or a certificate of authorization.
