Why a directive
Before 2019, each State applied its own rules of expert assessment: an opinion valid in Paris could be challenged in Singapore, a certificate accepted in Geneva refused in Nairobi. Buyers and sellers bore the cost of these divergences.
The directive establishes a common foundation: same principles, same method, same guarantees. It leaves States free to go further, but not to protect less.
