MR:
Intent to trespass
s.9(1)(a) - D enters a building or part of a building with the intent to commit theft, GBH or criminal damage
s.9(1)(b) - Having entered a building or part of a building as a trespasser, D attempts to steal, inflicts GBH or attempts to inflict GBH
If D enters a building with the intention to commit either theft, GBH or criminal damage, they will be liable for s.9(1)(a) but when they actually commit the offence, will be liable for s.9(1)(b) as well
If D enters a building with the intention to commit either theft, GBH or criminal damage, they will be liable for s.9(1)(a) but if they do not manage to commit the offence, they will only be liable for s.9(1)(a)
If D enters a building with the intention to commit either theft, but is unsuccessful and commits criminal damage instead, they will be liable for s.9(1)(a) and criminal damage because s.9(1)(b) does not cover criminal damage
If D enters a building with the intention to commit either theft but is unsuccessful and commits GBH instead, they will be liable for s.9(1)(a) and s.9(1)(b) as it covers GBH
