Re: How has he survived?
It is also important to remember that the EPO's internal rules, ESPECIALLY those relating to "disciplinary" actions, are far more draconian than would be permitted under EU law.
That summarizes the whole affair. I personally find it difficult to reconcile the concept of law and order (in intellectual property) being enforced by an organization which is not following law and order in its residence jurisdiction and looking to find excuses to do so.
While the stance of "we do not comply with labor law because we are international" may be allowed by legal theory, it is morally wrong for an international institution responsible for something in the Europe.
