Lord Janner, pictured, is alleged to have sexually assaulted young men in the 1970s and 1980s in children's homes in Leicestershire. His alleged victims could bring civil claims against him . Lord Greville Janner - the Labour peer accused of molesting young boys in the 1970s and 1980s - could be tested by experts to prove he has dementia as part of civil claims brought by his alleged victims, a lawyer has said. The family of the 86-year-old politician has been told he will not face child abuse charges because of his memory problems, but he could still face civil action from complainants. Legal firm Slater & Gordon are representing several people looking to take private action against Lord Janner, with police having identified 25 people who say the Labour peer attacked them. Each could claim up to £100,000. Lord Janner has been accused of preying on young boys at three Leicester care homes between 1969 and 1989, with prosecutors arguing there is 'overwhelming' cause to charge the former MP with 22 sex attacks on nine victims - the youngest aged just 10 at the time. Richard Scorer, head of the abuse team at Slater & Gordon, told Jamie Doward at The Observer newspaper that they were investigating the prospect of having Lord Janner examined by third-party expert witnesses. 'I have certainly dealt with civil claims before where the alleged abuser has claimed to have dementia and we have been able to have them medically examined in relation to that,' he said. 'It is something we could consider doing. It would depend on the detailed evidence that is available about his medical condition but, potentially, there is provision in the civil law for us to do that.' The director of public prosecutions Alison Saunder when she decided not to pursue the charges of historic sex abuse. She said there was 'no public interest' in prosecuting Lord Janner because of his dementia, adding that his illness made him unfit to plead - amid accusations of a 45-year cover-up over his alleged actions.

Prosecutors say there is substantial cause to charge Lord Janner with 22 charges of sexual assault on nine victims, but the director for public prosecutions sad the extent of his dementia made him unfit to face trial . Lord Janner with the Queen in 2003. In the same month his Westminster office was raiding by police the deeds to his £2million house were transferred to his children. Lawyers are questioning the extent of his dementia . Ms Saunder admitted that Lord Janner should have been prosecuted on three separate occasions - in 1991, 2002 and 2007, but botched investigations each time meant he escaped a prosecution. The CPS has been accused of double standards, after a MailOnline investigation revealed that at least 19 men with dementia have been convicted of child sex offences since 2010, including 10 in the last year. Lord Janner voted in the House of Lord 210 times between his Alzheimer's diagnosis and the end of 2013, leading some to suggest he could have been prosecuted if authorities had acted sooner. His alleged victims will be seeking compensation if evidence of wrongdoing is uncovered. The family of Lord Janner say he is innocent. However, this has been made more difficult since Lord Janner transferred ownership of his Hampstead Heath flat, estimated to be worth around £2million, in March 2014. The transfer took place in the same month that police raided the politician's office in Westminster . Director of public prosecutions Alison Saunders has come under fire for refusing to prosecute Lord Janner after saying his dementia would make him unfit to plead - admitting he should have been prosecuted before . Slater & Gordon represents 168 of Jimmy Savile's victims and 10 of former Liberal MP for Rochdale Cyril Smith. Mr Scorer said he believes it is 'outrageous' that allegations of sex abuse are only being investigated now, adding that the transfer of Lord Janner's assets would not put off the clients from pursuing legal actions. 'The question I would ask is: if he actually has dementia, on what basis does he have the capacity to transfer ownership of assets?' he said. There appears to be a contradiction between saying on the one hand that 'he has dementia' and on the other that he has been able to effect a transfer of assets. 'If there's evidence that the transaction has been done to avoid potential creditors that is something we could challenge.'
