I was looking at this case and found this:-
Does this mean we can now argue that the CSI does not have to be 'private'?But I would enter a caveat as to whether the Directive, when it speaks of "sickness insurance in respect of all risks" is necessarily speaking of private health insurance. The National Health Service, although now heavily funded out of general taxation, is in origin and in law based on national insurance. Nothing would have been easier, in the Directive and in the Rules, than to include the word 'private' if that alone was what was meant – especially since, so far as I know, private insurance rarely if ever covers all risks, such as the risk of requiring long-term medical care.
