After an extended period of negotiations with Haringey Council and the Mayor of London, leading to a Section 106 agreement, planning permissions were issued on 20 September 2011. Following the riots in Tottenham, other parts of London and elsewhere in England in August 2011, the Greater London Authority and Haringey Council announced on 28 September that it would relieve the club of all community infrastructure payments that planners would normally require, estimated at £8.5m, and to provide a further £8.5m for regeneration and infrastructure projects. On 11 July 2014 the Secretary of State for the Department for Communities and Local Government announced that a compulsory purchase order had been granted for the outstanding parcel of land required for the development of the new stadium site. In February 2015 this compulsory purchase order was subject to an unsuccessful legal challenge by the business that owned the land. The anticipated stadium opening date was revised several times.
