Statutory instrument can be laid under the negative procedure
After a proposed negative instrument has been laid, each House has ten sitting days in which it may consider the instrument and agree with the proposal of the Minister, or instead recommend the instrument be subject to the draft affirmative procedure. Any result of consideration does not bind a Minister, who must nevertheless make a written statement if disagreeing with a recommendation of a committee.
Actualise if neither House recommended affirmative or if they did a Minister disagreed. OR if one House recommended negative and the other House did nothing before the clock ran out. OR if both Houses did nothing before clock ran out
Date of the final decision OR the clock running out if one/both Houses did not consider.
