lack of clarity for actus reus
no definition of wounding in the Act, definition given by judge in JCC v Eisenhower
no definition of GBH given, 'really serious harm' DPP v Smith, 'serious harm' R v Saunders
focus on bodily harm, development has been piecemeal - developed bit by bit
1861, psychiatric (Burstow) and biological (Dica) GBH would not have been contemplated
Judges should apply law, Parliament create
breach of separation of powers
