Presented to Parliament by the Secretary of State for Foreign and Commonwealth Affairs by Command of Her Majesty, February 2016

2.1 The result of the referendum on the UK’s membership of the European Union will be final.

Government would have a democratic duty to give effect to the electorate’s decision. The Prime Minister made clear to the House of Commons that “if the British people vote to leave, there is only one way to bring that about, namely to trigger Article 50 of the Treaties and begin the process of exit, and the British people would rightly expect that to start straight away”.

The document you're quoting is not law. The referendum itself was non-binding.
