I am currently looking into Disability Discrimination Law in European countries and it seems that some are more compliant with the European Directive on Disability Discrimination than others.
Whilst CVD may not be recognised as a disability in the UK Courts (and I stress it has not been fully tested within the area of employment - the Strathclyde Police case seems to have gone quiet) it would undoubtedly fall within the definition of a disability in other countries. Therefore, it could be advisable to undertake your Class 1 Medical in one of those countries, keeping open the option that it may be possible to take the national aviation authority to Court on grounds of disability discrimination, should they refuse to issue a Class 1 medical purely on CVD grounds.
My resources are limited therefore I don't expect my research to be completed in the immediately foreseeable future, however, maybe the CVDPA could look further into this.
