1.22.

The draft Bill published on 4 November 2015 received pre-legislative scrutiny
from the ISC, the House of Commons Science and Technology Committee and a
Joint Bill Committee of both Houses. Each of those committees reported in
February 2016,29 and their recommendations were reflected in the Bill introduced
on 1 March. Between second reading on 15 March and report stage on 6-7
June, a House of Commons Public Bill Committee considered the Bill over 16
half-day sittings.30 The Joint Committee on Human Rights produced its own
report on 2 June.31 Further reports on specific aspects were issued in July 2016
by the House of Lords Constitution Committee32 and the House of Lords
Delegated Powers and Regulatory Reform Committee.33 The first five of these
seven committees took written and oral evidence, which save in the case of the
ISC (whose inquiry was into classified issues and which accordingly took
evidence only in closed session) was published on their websites. The written
evidence and transcripts of oral evidence before the Joint Bill Committee alone
occupy 2,364 pages.34

Genesis of the Review

advanced.

Terms of reference (Annex 2) were subsequently agreed by the Prime Minister,
and the Review was announced by the Home Secretary when the Bill reached
report stage in the House of Commons, on 7 June 2016. An exchange of letters
dated 6 June 2016 between Sir Keir Starmer QC MP, Shadow Home Office
Minister, and Rt. Hon. John Hayes MP, Minister of State for Security (Annex 3),
was placed in the House of Commons Library. I undertook to complete the
