Commentaries: Art. 89

Where, following consideration of a bill, there are differences between the councils, the divergent decisions of each council shall be referred to the other council for consideration, until agreement is reached between the two councils.
Following the initial consideration in each council, any further consideration shall be limited exclusively to the issues on which no agreement has been reached.
A council may reconsider any other issue only if this becomes necessary as a result of decisions taken in the intervening period or if the preliminary consultation committees of both councils move jointly for the issue to be reconsidered.
