Calocane, 32, had been diagnosed with treatment-resistant paranoid schizophrenia before the attacks.
In addition to killing Mr Webber, Ms O’Malley-Kumar and Mr Coates, Calocane stole Mr Coates’s van and used it to drive at three pedestrians, who were all left seriously injured.
The review into the sentence was held by the Lady Chief Justice of England and Wales, Lord Justice Edis and Mr Justice Garnham.
In summing up their conclusion, Baroness Carr said: “Had the offender not suffered the mental condition that he did, the sentencing judge would doubtless have been considering a whole life term.
“But neither the judge nor this court can ignore the medical evidence as to the offender’s condition which led to these dreadful events or the threat to public safety which the offender continues to pose.”
