Earlier in the day, UK Prime Minister David Cameron called on Brussels to fast-track the creation of the PNR directive, which is similar to the Data Retention Directive. The latter involves 14 out of the 28 EU member states setting up their own national passenger name record system covering flights in and out of their own country.
"The ruling of the Court of Justice of the European Union invalidating the Data Retention Directive casts doubt on the legality of the EU PNR Directive. Another problems of the proposal are the lack of evidence showing that these measures are effective and excessive costs," McNamee said.
The European Parliament is set to adopt the informal text of the EU PNR Directive on Thursday.
The EU PNR Directive was first proposed in 2011 and a fast-track procedure to adopt the proposal was introduced after the November 13 Paris attacks, which claimed the lives of 130 people and injured over 350.
