On 1 May 2018, the day on which the ISS Act 2017 came into force, the Oversight Department of the CTIVD started its oversight activities into the ‘functioning of the ISS Act 2017’. The Oversight Department focuses on how the ISS Act 2017 is implemented and carried out by the AIVD and the MIVD. This process will take two years and the CTIVD will report to Parliament and the Ministers involved on the results every six months, in November 2018, May 2019, November 2019 and May 2020. This is the first report, published in Dutch on 4 December 2018.
