Mother who stabbed man to death during a psychotic episode loses sentence appeal

Christina Anderson was jailed for eight years for the manslaughter of Gareth Kelly, 38, while he tried to start his car outside her home in the early morning of February 25, 2020

Christina Anderson was sentenced last year to 11 years in prison with the final three suspended for four years.

A mother of three who stabbed a man to death outside her home during a psychotic episode has lost an appeal against the severity of her eight-year prison sentence.

Christina Anderson, 41, of Brownsbarn Wood, Kingswood, Dublin 22, had never met father of seven Gareth Kelly, 38, when she twice attacked him, stabbing him five times in total, while he tried to start his car outside her home in the early morning of February 25, 2020.

She was initially charged with murder and pleaded not guilty by reason of insanity. 

In January last year, more than one month into her trial, the Director of Public Prosecutions accepted a plea of guilty to manslaughter by reason of diminished responsibility due to a mental disorder. 

The State accepted Anderson was experiencing a psychotic episode due to bipolar affective disorder but did not qualify for the full defence of a not guilty by reason of insanity verdict under the Criminal Law (Insanity) Act. 

The State also accepted cannabis intoxication "does not feature" in the offence, despite telling the jury during her trial a central issue was whether Anderson's actions were driven by mental illness or by cannabis intoxication.

Moral culpability

Her lawyer, Michael O'Higgins SC, had argued at the three-judge Court of Appeal that the sentencing judge, Ms Justice Karen O'Connor, did not correctly assess the level of his client's moral culpability before calculating the sentence.

He said a previous decision by the Court of Appeal had stated that where diminished responsibility arises as a defence, moral culpability can be "extinguished altogether". In Ms Anderson's case, counsel said "moral culpability is at the lowest possible point".

He drew the court's attention to a report written by consultant psychiatrist Dr Brenda Wright, who said Ms Anderson was "highly dominated by her mental condition", which the psychiatrist said was "so severe that she was experiencing delusions into which she had no insight".

Ms Anderson had a "psychotic moral justification" for her actions because, Dr Wright said, "she delusionally believed" her life and the lives of her children were in danger and that she could protect them by killing Mr Kelly.

Delivering Tuesday's judgment, Ms Justice Isobel Kennedy said this was a "profoundly sad and tragic case". In the absence of a mental disorder, Ms Justice Kennedy agreed with the trial judge that the headline sentence would have been at the "very top end" for manslaughter at 20 years' imprisonment. 

Ms Justice Kennedy further agreed with the sentencing judge that, having considered the mental disorder, the headline should be reduced to 13 years.

Mitigating factors

Ms Justice Kennedy said the sentencing judge had then considered mitigating factors, including the guilty plea and that Anderson had no previous convictions, was a mother who home-schooled her children and had a good work history. Ms Justice O'Connor therefore reduced the sentence to 11 years and suspended the final three for four years on various conditions.

Ms Justice Kennedy said it was difficult to see how a person convicted of manslaughter due to diminished responsibility could be said to have their moral culpability entirely extinguished. 

She said the trial judge had properly reduced the headline sentence, having taken into account that Ms Anderson's mental state was "highly dominated" but not "entirely dominated" by her mental condition. 

The "substantial reduction" amounted to more than one third of the headline sentence and therefore "properly reflected her mental condition", Justice Kennedy said.

The discount for mitigating factors, Justice Kennedy said, was "entirely within the discretion" of the sentencing judge and was not an error in principle. 

Ms Justice O'Connor took considerable care in coming to the final sentence, the appeal court found. Dismissing all grounds of appeal, Ms Justice Kennedy said the sentence was proportionate.
