Sam Harris was injured while playing on a bouncy castle when he was 11 years old (in 2006). He was accidentally kicked in the head by a 15-year-old and now needs round the clock treatment.

The bouncy castle had been hired by Catherine and Timothy Perry for their triplets’ tenth birthday party. Sam got on to it after asking Mrs Perry for permission. He had earlier been playing football in an adjoining field with his father who was also made a defendant in the case which was brought by Sam through his mother, Janet Harris.

The case against Mr Harris was dismissed but the Perrys were held liable for not supervising the children properly especially in light of the fact that the castle came with instructions not to allow rough play on it or mix children of different sizes.

The High Court has given the Perrys permission to appeal. If an appeal is not pursued, Sam is to receive an interim payment of £100,000.
