The decree issued ahead of the Dec 1 election reduced the number of candidates a voter can pick up from a maximum of four to only one.
Under the law, all Amiri decrees issued in the absence of the Assembly must be submitted in the first session when the Assembly meets and it has the right to approve or reject the decrees.
The opposition boycotted the election due to the amendment, claiming that it allows the government to manipulate the outcome of the election.
Even after the election, the opposition has continued to stage protests calling for scrapping the new Assembly and repealing the amendment decree.
The approved decree now goes to the Assembly which will vote on it to approve or reject it. If the decree is rejected, which is a very remote possibility, it will mean nullifying the results of the election and dissolving the Assembly.
Dozens of challenges against the decree were submitted to the constitutional court alleging that the amendment breaches the constitution.
