To the extent that it applies to third-country nationals who do not fulfil or who no longer fulfil the conditions of entry in accordance with Regulation (EU) 2016/399, this Regulation constitutes a development of the provisions of the Schengen acquis in which the United Kingdom does not take part, in accordance with Council Decision 2000/365/EC [8]; the United Kingdom is therefore not taking part in the adoption of this Regulation and is not bound by it or subject to its application.
A mhéid atá feidhm aige maidir le náisiúnaigh tríú tír nach gcomhlíonann nó nach gcomhlíonann a thuilleadh na coinníollacha maidir le dul isteach i gcomhréir le Rialachán (AE) 2016/399, is é atá sa Rialachán seo forbairt ar fhorálacha acquis Schengen nach bhfuil an Ríocht Aontaithe rannpháirteach iontu, i gcomhréir le Cinneadh 2000/365/CE ón gComhairle [8]; dá bhrí sin, níl an Ríocht Aontaithe rannpháirteach i nglacadh an Rialacháin seo agus níl sí faoi cheangal aige ná faoi réir a chur i bhfeidhm.
