Lawyers for an insurance firm have issued a high court writ, against the mother whose son was killed in a motorcycle accident, claiming that her son was not properly insured.

John Rogerson, 40, was killed in a motorcycle accident with his girlfriend Jacqueline Arthur in April last year.

GHL Insurance Services are suing Mrs Rogerson, of Riverside, Great Clifton, as the personal representative of her late son's estate. The writ accuses Mr Rogerson, a former bouncer and driving instructor, of making a false statement to obtain bike insurance for the Kawasaki machine on which he died.

The company, based at Haywards Heath in West Sussex, wants a legal ruling that says it is entitled to avoid paying out on his insurance policy.

It says this is because Mr Rogerson obtained it by failing to disclose material facts, and making a false statement.

The company says that the information he provided was incorrect, and that he was not the registered owner or keeper of the machine, which was owned by Graeme Cameron, who had allowed him to borrow the Kawasaki. Mr Rogerson knew that he was he not the owner or keeper, and that he had not just bought it, and was under a duty to disclose all material facts, the writ claims.

GHL says it was induced to provide insurance cover by his claim that he owned the bike, but says that if it had known he did not own the machine, it would not have provided him with insurance.
