Delegated legislation published on

FOI request reference: CAS-66330-J3V6F2
Publication date: January 2021

I would like to request under the Freedom of Information Act 2000 the following statistical information about delegated legislation published on

1. The number of correction slips issued
2. The number of instruments issued under the ‘free issue’ procedure to correct defects in other instruments
3. The number of corrective reprints of instruments
4. The number of instruments removed from due to being invalid (e.g. the Minister signed a different draft to that approved by Parliament, or a court found the instrument totally ultra vires, or any similar thing)
5. The number of unused SI numbers, i.e. ones issued to departments but then subsequently not published and/or gaps in the SI numbering sequence

I would request this on a year by year basis, going back as far as the cost limit allows or until the data no longer exists. In addition, I would prefer the statistics broken down by SI, SSI, and SR.


Your request has been handled under the Freedom of Information (FOI) Act 2000. The FOI Act gives you the right to know whether we hold the information you want and to have it communicated to you, subject to any exemptions which may apply.
