Requests for comparison with data stored in Eurodac should be made by the operating units within the designated authorities to the National Access Point, through the verifying authority, and should be reasoned. The operating units within the designated authorities that are authorised to request comparisons with Eurodac data should not act as a verifying authority. The verifying authorities should act independently of the designated authorities and should be responsible for ensuring, in an independent manner, strict compliance with the conditions for access laid down in this Regulation. The verifying authorities should then forward the request, without forwarding the reasons for it, for comparison through the National Access Point to Eurodac following verification that all the conditions for access have been fulfilled. In exceptional cases of urgency where early access is necessary to respond to a specific and actual threat related to terrorist offences or other serious criminal offences, it should be possible for the verifying authority to forward the request immediately and only carry out the verification afterwards.
