Division 2.15 Flagging
United Kingdom
A flag shall be added at the request of another Member State.
Articles 94(4), 95(3), 97 and 99(6) of the Schengen Convention allow a Member State to refuse to perform a requested action on its territory at any time by requesting that a flag be added to the alerts in accordance with Articles 95, 97 or 99 where it considers that an alert is incompatible with its national law, its international obligations or essential national interests. The reasons for the request shall be provided simultaneously.
When a flag is added to Articles 97 and 99 alerts the alert does not appear on the screen when the end user consults the system. An alternative procedure exists only for Article 95 alerts. Each Member State shall detect the alerts likely to require a flag as swiftly as possible.
