The renegotiation agreement could yet fall through  At the moment is simply an agreement between the leaders of the states within the EU. Until it is written into treaties the agreement is vulnerable. There are two ways in which it could fall through or be changed. The first is for the European Court to declare part of it incompatible with the EU treaties. The Secretary of State for Justice Michael Gove has argued "The facts are that the European Court of Justice is not bound by this agreement until treaties are changed and we don't know when that will be". [1]  The second is that the European Parliament still needs to approve as would any legislature when given a proposal by the executive branch. [2] Members of the European Parliament have refused to rule out that it could be rejected. [3] Even then nothing is secure until there is treaty change as the only way the agreement can be legally binding “would be through Treaty amendment, or the equivalent agreement of a Protocol.” [4]  [1] ‘EU reforms ‘not legally binding’ – Michael Gove’, BBC News, 24 February 2016,   [2] Peers, Steve, ‘The draft UK/EU renegotiation deal: is it ‘legally binding and irreversible’?’, EU Law Analysis, 10 February 2016,   [3] Stone, Jon, ‘David Cameron’s EU deal can’t be legally binding, EU Parliament president Martin Schulz says’, Independent, 16 February 2016,   [4] European Scrutiny Committee, ‘Voters must know EU changes will require Treaty amendment’, parliament.uk, 15 December 2015,
