Article 10(1) of the Protocol provides that the provisions of the Schengen acquis shall be put into effect by the Principality of Liechtenstein only pursuant to a Council decision to that effect after verification that the necessary conditions for the implementation of that acquis have been fulfilled by the Principality of Liechtenstein.

On 9 June 2011, the Council concluded that the Principality of Liechtenstein had fulfilled the conditions in the area of Data Protection. It is therefore possible to set a date from which the Schengen acquis relating to the Schengen Information System (SIS) may apply to the Principality of Liechtenstein.

The entry into force of this Decision should allow for real SIS data to be transferred to the Principality of Liechtenstein. The concrete use of these data should allow the Council, through the applicable Schengen evaluation procedures as set out in the Decision of the Executive Committee of 16 September 1998, to verify the correct application of the provisions of the Schengen acquis relating to the SIS in the Principality of Liechtenstein. Once those evaluations have been carried out, the Council should decide on the lifting of checks at internal borders with the Principality of Liechtenstein.

The Agreement between the Principality of Liechtenstein, the Republic of Iceland and the Kingdom of Norway concerning the implementation, application and development of the Schengen acquis and concerning the criteria and mechanisms for establishing the State responsible for examining a request for asylum lodged in Liechtenstein, Iceland or Norway stipulates that it shall be put into effect in respect of the implementation, application and development of the Schengen acquis on the same date as the Protocol is put into effect.

A separate Council Decision should be adopted setting a date for the lifting of checks at internal borders. Until the date set out in that Decision, certain restrictions on the use of the SIS should be imposed,
