You can read the detailed judgement of the Supreme Court here and the summary by the FCA here.
In light of the ruling today, the DLA technical team are going to review the detailed judgment and talk to all three main insurance companies (UK Special Risk, Towergate and Weald). As with the initial FCA legal review, the DLA had a mixed response the insurance companies in terms of the level of engagement and information offered, therefore if it appears that one insurance company is being covered more than another, this will purely be down to the level of engagement they have made with the DLA.
We will, as always, report back to DLA members once we have any more details.
