The declaration shall be accompanied by the opinion of the delegating federation competent to lay down the technical and safety rules for the discipline for which it has been delegated.
The request for an opinion must be sent by registered letter with acknowledgement of receipt or delivered by hand against receipt, to the relevant delegating federation, prior to the declaration to the Prefect. The federation must give its opinion within fifteen days. If the federation does not give its opinion within this period, the opinion is deemed to be favourable.
When the event is organised by an approved federation, its regional or departmental bodies or one of its members, the opinion provided for in the first paragraph is deemed to be favourable when an agreement is in force, in the discipline which is the subject of the event, between this federation and the competent delegating federation guaranteeing the implementation by the approved federation of the technical and safety rules laid down by the delegating federation concerned.
