Tim has been charged with criminal damage, a triable either way offense. At the plea and directions hearing, Tim must decide whether to plead guilty or not guilty. If guilty, the magistrates court would determine if it has sufficient sentencing powers. If not guilty, a mode of trial hearing would be held to determine whether the case is heard in magistrates or crown court based on factors like representations, case complexity, and Tim's criminal history. The crown court has more severe sentencing powers but a trial may take longer, while the magistrates court has a quicker process but less sentencing power for higher value damage.
