Personal Injury analysis: Isaac Hogarth, barrister, of 12 King's Bench Walk, examines a High Court master's refusal to grant the claimant motor insurer a declaration that it was not liable to indemnify the first defendant, who had crashed someone else's car. The claimant insurer had sought a declaration even though the first defendant had a policy with the claimant which covered his driving other cars (DOC). The master also set aside the claimant's notice of discontinuance.
