Yes that’s correct. The issue is the election system we have. You can elect to go to the Crown Court which is for serious cases. The delay is now so long that you end up with years of delay, where witnesses decide to drop out, or they are intimidated out of the process. The victim themselves may decide not to participate.
This is a huge advantage to a defendant because the longer it takes, the more chance it may never actually happen.
Jury trials were also suspended in NI with Diplock courts. So there is some precedent.
Because on conviction you have a right of appeal the chances are this is human rights compatible and I imagine they would select offences that can be considered in the mags now but need to go to the Crown Court for sentencing. That would be legal I think.
