translate English to French: However, where the institutions of other Member States raise doubts as to the correctness of the facts on which the certificate is based or as to the legal assessment of those facts and, consequently, as to the conformity of the information contained in the certificate with Community legislation, the issuing institution must re-examine the grounds on which the certificate was issued and, where appropriate, withdraw it.
Toutefois, lorsque les institutions des autres Etats membres font valoir des doutes sur l'exactitude des faits sur lesquels repose le certificat ou sur l'appréciation juridique de ces faits et, en conséquence, sur la conformité des mentions dudit certificat avec la réglementation communautaire, l'institution émettrice est tenue de réexaminer le bien-fondé de celui-ci et, le cas échéant, de le retirer.
