Absolutely deserved jail - probably longer.
Think of the inconvenience, maybe even suffering, this causes to any victims and witnesses, who suffer from the delay and perhaps having to give their evidence again at a new trial. Likewise, additional delay, uncertainty and inconvenience for the individual on trial.
Then there are the many thousands of pounds of wasted costs for paying the judge, court staff, barristers, solicitors etc.
I struggle to think of more selfish, entitled behaviour.
