Causation No.1

In law, everyone knows that causation is difficult. When studying negligence, it is by far the most difficult part of any problem question to try to work out whether the injury was actually caused by the negligent act or not. It is so complicated, in fact, that the courts are sometimes forced to award compensation when they cannot know with absolutely certainty whether the defendant is actually to blame. I have spent the last week or so trying to get my head round this disorienting reality only to discover that the House of Lords have suddenly decided to change the law only three weeks before my exam. Aaaargh!
