Unfortunately, this is typical DM reporting - short on the facts and with lots of nonsense.
Firstly, it has ALWAYS been the case that a Defendant may be tried in a criminal court in his absence and without representation. As long as the Court is satisfied that the Defendant knew of the proceedings and has sought to make himself absent the trial may go ahead. Otherwise, no trial would ever go ahead since Defendants would just absent themselves. However, this is not a criminal Court.
The piece of legislation that the DM refers to is the Mental Capacity Act 2005. That legislation repealed certain other bits of legislation and consolidated them. The Court of Protection is not new by any means - and it has always had the inherent power to punish contempt by imprisonment. The Act went through the normal consultation process, but because the changes weren't as huge as the DM makes out, no one really noticed. So wrong again DM.
This person WILL have been aware of the Court hearing - indeed, I suspect that this will have the last in a long line of Court hearings. The Judge would have had to have been thoroughly satisfied that she was aware of the hearing and chose to absent herself. Had she been present, the Judge would have adjourned the hearing to give her the opportunity to get legal advice. I also suspect that the Judge finally reached the end of his tether in this woman's persistent breach of Court Orders.
Unfortunately, this type of skewed shabby journalism (I use that word in its loosest sense) just seeks to scaremonger and mislead.
