in what context? there are a whole list of people who can enter your house with good reason. If it is built on National Trust (for instance) property then there are conditions attached to that, however you may allow your pit bull to be unmuzzled in your own house and (enclosed) garden. Entry into your house or garden is trespass, but I believe that this is a civil and not a criminal matter. That's the extent of my knowledge, someone else have a go !
define 'house', define 'private', define 'on' and define 'land'. land law is not too complex but it often very dull and your question is too broad to be answered with anything short of a 10,000 word essay. define your terms and i'll have a go :-)
Is your house on the M1? the M25? in the Serpentine? on top of the Old Bailey? in the Thames? on Heathrow Runway 5? on a Cross Channel Ferry? or attached to the London Eye?. If your answer to any of these is "yes" then you are probably not on private land.
Trespass to land (invasion of possession etc) is not a crime, wolfgang. Trespass to person (assault and battery etc) is a crime. Entering a building without consent or by fraud is a crime.
sorry, i am not an expert, but i thought that was what a civil matter meant? that you can sue for trespass, but if you can't show a consequent loss, then you are not likely to get anywhere??
Your statement, wolfgang, is true only so long as it falls under the maxim " the law will not concern itself with utter trifles ". In crude round figures there are !00 different trespasses to land and 100 claims arising therefrom. Also, although trespass to land was removed from the crime list a long time ago, in harsh fact many trespasses to land (easily) become criminal under other acts.
