During May 1968, SAC members, disguised as ambulance crew, took demonstrators to their headquarters, rue de Solférino, where they were beaten up. They then prepared the Gaullist counter-demonstration which assured de Gaulle of the support of (parts of) the French people. After the June 1968 legislative election, the SAC expelled from the Youth Centres (""Maisons des Jeunes"") various movements and associations, including the Maoists and the so-called "Katangais". Continuing this "policy of order", the SAC created in 1969 the right-wing students' union "Union Nationale Inter-universitaire" (UNI) in 1969 to counter the "leftist subversion" in the students' movement. Until 1976, the SAC supported the UNI in daily organisation, while many UNI members were also SAC members. Double membership of most activists continued after 1976, but the two organisations had distinct leadership.
