There may be some interesting long term implications in this piece of news:
The European Commission is proposing a legal framework for a European research infrastructure (ERI) more adapted to the needs of such facilities. This new legal framework will provide a legal personality recognised in all Member States.
It will reflect the spirit of a truly European venture, but will still allow the participation of non-European countries. Flexible enough to adapt to the requirements of the different facilities, it would be easy to use. Some of the privileges and exemptions of international organisations (e.g. VAT exemption) could be provided, which would facilitate negotiations between the countries involved.
