As Bo Xilai stood in court to receive his life sentence last month, there could be no mistaking the faint smile of the Chinese politician who seemingly fell victim to his own political success.
But despite the unusually public nature of his demise, many in China were unconvinced that the man appearing in court would serve the punishment. Throughout the trial, posts on social media demanded to see pictures of Bo in his cell to prove that he was really there. The online claims levelled against his wife, Gu Kailai, at her trial hinted at a greater level of deception - that she was not in court at all.
These allegations may seem far-fetched, but they are based on what many perceive to be a growing phenomenon. Media reports of ding zui (literally "substitute criminal"), where hired stand-ins take the place of offenders, suggest that such immunity to the legal process can be acquired with sufficient money or influence.
A 2009 case involving an official in Anhui province showed the influence that the powerful can exert to redirect blame. Reversing his car at high speed, the former head of Yijiang's district court, Ding Shuming, killed one person and injured two others in a road accident. He arranged for his usual driver, Zhong Ming, to report the incident to the police and take responsibility for the accident. Zhong agreed, though a late act of conscience from Ding two days later ensured that the right man appeared in court. He received three years' jail.
Other attempts at ding zui give an indication of the sums of money that may be involved. An uninsured coach driver in Gansu province, Li, killed one person and injured another after he crashed into the back of a motorcycle in July 2012. As he awaited the police, Li pleaded with one of the coach's passengers to take his place and go to court, offering 150,000 renminbi ($29,000) in return. As the evidence was prepared for the hearing, inconsistencies emerged. Only after several rounds of questioning did the passenger confess to the scam leaving Li to face trial.
