While not being a formal ECJ judgement, it was seen as a good indication of the court's eventual decision. On 10 December the ECJ decided that a notice of withdrawal can be revoked unilaterally, i.e. without approval by the other EU members, provided that the decision to revoke is made according to the country's constitutionally established procedures. The case now returns to the Court of Session, to apply this ruling. The British Government immediately affirmed that it did not intend to propose revocation. Article 50 allows the maximum negotiation period of two years to be extended by a unanimous decision by the European Council and the state in question. For Brexit this has been done three times.
