text: The 1965 agreement was a source of contention for the Parliament, which wished to be closer to the other institutions, so it began moving some of its decision-making bodies, committee and political group meetings to Brussels. In 1983, it went further by symbolically holding a plenary session in Brussels, in the basement of the Mont des Arts Congress Centre. However, the meeting was a fiasco and the poor facilities partly discredited Brussels' aim of being the sole seat of the institutions. Things looked up for Brussels when, in 1985, the Parliament gained its own plenary chamber in the city (on the /) for some of its part-sessions. This was done unofficially due to the sensitive nature of the Parliament's seat, with the building being constructed as an "international conference centre". When France unsuccessfully challenged the Parliament's half-move to Brussels in the Court of Justice, the Parliament's victory led it to build full facilities in the city.
  Edinburgh European Council compromise
  In response the Edinburgh European Council of 1992, the EU adopted a final agreement on the location of its institutions. According to this decision, which was subsequently annexed to the Treaty of Amsterdam in 1997, although the Parliament was required to hold some of its sessions, including its budgetary session, in Strasbourg, additional sessions and committees could meet in Brussels. It also reaffirmed the presence of the Commission and Council in the city.
