Hi Bobo - a case to get your teeth into
The analysis is not correct ( the forms of action are dead and yet rule us from their grave ) ( Maitland Forms of action at common law 1909)
but tot up the forms of action - contract, trespass to person, assault, animal trespass, horse stealing etc
and the only one that is a go-er is - Negligence
Were you cutting your nails negligently?
Leaving the window open negligently I think is not enough
Then is the damage foreseeable
er Nettleship v Weston I think
and is it not too far away - (nail files causing rain crashed in Euston I suggest WOULD - be too far)
and bobs your uncle = £1000 please and worth every penny
