On the abolition of the certificate under Article 75 of the Schengen Convention 

According to the petitioner, under Article 75 of the Schengen II Convention, patients who require narcotic drugs and who travel with them to Schengen States must be able to provide a certificate. This must be issued by a doctor and authenticated by a public authority. This makes it impossible to travel on a spontaneous basis. Moreover, the duration of the trip and validity of the certificate (of a maximum of 30 days) must be indicated in advance. The petitioner considers that this rule violates the right to free movement and calls on the European Parliament to make a change to this rule so that persons who rely on narcotic drugs may also travel to Schengen States without being required to obtain a certificate beforehand.
