The 40-year-old Hells Angel stands accused of murdering two members of the rival Outlaws gang and an Outlaws supporter.
On 20 May 2011 Outlaws "full member" Freddy Put, "hangaround" and pub landlord Jef Banken and supporter Michael Gerekens were shot dead on an industrial zone in Maasmechelen where the Outlaws were holding an opening reception for a new tire centre.
During the opening session Ali Ipekci's lawyer insisted that the defendant's rights under the Salduz Law had been violated because he was not accompanied by his lawyer during several questionings.
Ali Ipekci's counsel argued that he had been questioned on several occasions without his lawyers being present and was not always cautioned.
Under the Salduz Law all suspects must get access to legal counsel before and during each and every interview. The law did not yet apply at the time of Ali Ipekci's arrest but his counsel argued that Belgium was obliged to follow the relevant EU legislation. It argued that evidence from the controversial interviews could not be used in court.
