8.  Prior to those demonstrations, on 18 March 2011, 11 April 2011 and 15 October 2012 respectively the organisers had given notice to the relevant authority, the Baku City Executive Authority (“the BCEA”).
9.  The BCEA refused to authorise those demonstrations at the places indicated by the organisers and proposed a different location on the outskirts of Baku – the grounds of a driving school situated in the 20th residential area of the Sabail District.
10.  The organisers nevertheless decided to hold the demonstrations as planned. According to the applicants, the demonstrations were intended to be peaceful and were conducted in a peaceful manner. The participants were demanding democratic reforms in the country and free and fair elections, and protesting against impediments on freedom of assembly.

The information about the rally was sent to the GDEA by post and the fourth applicant’s home address was indicated (for reference) as the address of the sender.

15.  As mentioned above, the demonstration of 2 April 2011 was attended by the second applicant; the demonstration of 17 April 2011 was attended by the first and third applicants. However, the police began to disperse those demonstrations as soon as the protesters began to gather.
16.  The circumstances related to the dispersal of the demonstrations of 2 April and 17 April 2011, the first, second and third applicants’ arrests and custody, and subsequent administrative proceedings against them are similar to those in Gafgaz Mammadov v. Azerbaijan (no. 60259/11, 15 October 2015) (see also Appendix).

He also submitted a photograph in which he is shown with bruises on his body.
21.  The applicants raised their ill-treatment complaints during the administrative proceedings following their arrest on 17 April 2011. Namely, in their appeals against the first-instance court’s decisions the applicants complained that they had been ill-treated during their police custody, and requested the Baku Court of Appeal to order a forensic examination of their injuries, to question particular witnesses and to obtain the review of the medical records drawn up at their check-in to a detention facility where they had served their sentence.
22.  On 21 April and 4 May 2011 respectively the Baku Court of Appeal dismissed the applicants’ appeals and upheld the decisions of the first‑instance court (see Appendix).
The appellate court disregarded the applicants’ ill-treatment complaints and their requests related to those complaints.
23.  On an unspecified date the applicants lodged a complaint before the General Prosecutor’s Office asking it to conduct an investigation into the alleged ill-treatment.
24.  On unspecified dates, the applicants were summoned to the Nasimi District prosecutor’s office and questioned in connection with their complaint of ill-treatment.
