According to HUDOC's press release:

The applicant, Montassar Makdoudi, is a Tunisian national who was born in 1989 and lives in Monastir (Tunisia). Mr Makdoudi complained about a removal measure issued against him by the Belgian authorities together with a 10-year ban on residence on account of his conviction for various offences committed in Belgium, and the national authorities’ refusal to take into account the fact that he is the father of a child with Belgian nationality. Mr Makdoudi allegedly arrived in Belgium in 2008. He was arrested in 2009, and then sentenced in 2010 to 42 months’ imprisonment. He served his sentence until December 2012. In the meantime, in 2011 he officially acknowledged paternity of a girl with Belgian nationality, born on 15 March 2010. A ministerial deportation order was issued against him in 2011, followed by several orders to leave the country, the last of which was issued in June 2016; Mr Makdoudi returned to Tunisia on 27 July 2016. Relying on Article 5 § 4 (right to a speedy decision on the lawfulness of detention) of the European Convention on Human Rights, Mr Makdoudi complained that the remedies he had used to challenge the lawfulness of his detention in a closed centre for aliens pending removal (from 15 May to 11 September 2014) had not enabled the domestic courts to take a final decision on this matter. Relying in particular on Article 8 (right to respect for private and family life) of the European Convention, he complained about his removal to Tunisia coupled with the ban on residence, and the national authorities’ refusal to take his paternity into account.
