The EPO staff has no fundamental rights at all.
I read in the comment of Int.og: ¨ The host country may not be able to do anything directly, but as with anyone under diplomatic immunity they could say that he is no longer welcome, and ask him to leave.¨. This could surely be a possible reaction of Germany and The neteherlands.
The German prime minister Angela Merkel said to the new US President Trump:
"Germany and America are bound by common values — democracy, freedom, as well as respect for the rule of law and the dignity of each and every person, regardless of their origin, skin color, creed, gender, sexual orientation, or political views. It is based on these values that I wish to offer close cooperation, both with me personally and between our countries’ governments.”
Mr Heiko Maas, Federal Minister of Justice and Consumer Protection is well informed that there is a bad copy of Donald Trump President of the European Patent Office: namely Benoit Battistelli of french nationality. He is a bad copy because he has no respect for the rule of law, even not for the European Patent Convention, and the dignity of each and every person.
A nice overview you can find in the document for the Bavarian State Parliament published on 02 February 2017: Request - finally ensure the fundamental rights of the staff of the European Patent Office! https://www.bayern.landtag.de/www/ElanTextAblage_WP17/Drucksachen/Basisdrucksachen/0000009500/0000009748.pdf
It is for me and many others not clear what the reason is why Mr. Maas did nothing until now and many people working at the EPO have to suffer day after day.
