The Czech government is proposing to amend the country’s constitution to make the vote of no-confidence “constructive”:
If the opposition wants to propose a no-confidence vote, it must agree on the name of the future prime minister and have this agreement signed by at least 50 lower house deputies, according to the government’s draft amendment.
If a no-confidence vote fails, the opposition may not propose a new vote sooner than after six months or when 80 deputies support its proposal. (Prague Monitor)
The Czech proposal is more restrictive (constrictive?) than the other two longest-existing provisions for constructive votes. For example, under Article 67 of the German constitution, there is neither a stipulated minimum number of legislators who must propose a no-confidence vote nor a limitation on future motions if a motion fails. In Spain’s constitution, Article 113 requires a minimum one-tenth of the chamber to propose a motion against the government, compared to one-fourth in the Czech proposal. There is in Spain a prohibition on the same signers of a failed motion proposing another one in the same parliamentary session.
While a constructive-vote provision along the lines of Germany’s seems like a good idea to me, I am very skeptical of provisions that make it considerably more difficult for a parliamentary majority to remove a government. The more restrictions there are on parliament’s rights in this area, the more the system shades towards separate survival in power of the executive and legislature–thereby undermining the critical accountability feature that makes a democracy parliamentary.
To pass, the Czech proposal would need support from the leftist opposition, as the government is well short of the necessary three-fifths majority for constitutional changes.
UPDATE: As Robert Elgie notes in a comment, the Czech Republic is already moving to direct election of the president. Thus the country will join Poland in having the unusual combination of both semi-presidentialism and constructive vote of no confidence.
