A father who shook his six-month-old son with the force of a "high-velocity car accident" after consuming 11 pints of lager and cocaine has had his jail sentence increased. Christopher Yates, 30, was initially sentenced to four years in prison but his term has now been extended to six years.

Lady Chief Justice Baroness Carr stated that the original sentence was "not only lenient but unduly so." The incident left the baby with severe brain injury, blindness, and a likely inability to walk. The court heard that Yates shook the infant multiple times, yelling at the child, and then delayed calling for an ambulance for over six hours, initially claiming the baby had fallen. Yates later admitted to causing serious physical harm to a child.

The baby had been in foster care but was placed in Yates's sole custody three weeks prior to the incident, despite concerns from family members about his heavy drinking and other "red flags." These concerns included Yates becoming frustrated with the child, not dressing him properly, and maintaining a living space described as a "mess" with dirty nappies and empty alcohol cans. When questioned about his drinking, Yates reportedly told a relative, "I can do whatever I want."

Lawyers for the Solicitor General argued that the sentencing judge did not adequately reflect the severity of the harm caused and reduced the sentence too much to account for Yates's ADHD, autism, depressive disorder, and traumatic upbringing. They emphasized the "very significant use of force against a six-month-old baby which resulted in catastrophic injury."

Yates's defense noted that the sentencing judge had appropriately considered his mental health conditions. They also highlighted that authorities were aware Yates was "self-medicating" with alcohol during the assessment process for custody, a behavior he had engaged in for a significant portion of his life. The defense suggested that greater professional monitoring and guidance earlier on could have potentially helped Yates manage his behavior and care for the child.
