The three communities merged their remaining organs as the European Communities in 1967, and the body's name was changed to the current "European Parliament" in 1962. In 1970 the Parliament was granted power over areas of the Communities' budget, which were expanded to the whole budget in 1975. Under the Rome Treaties, the Parliament should have become elected. However, the Council was required to agree a uniform voting system beforehand, which it failed to do. The Parliament threatened to take the Council to the European Court of Justice; this led to a compromise whereby the Council would agree to elections, but the issue of voting systems would be put off until a later date.
