Central Party 1999 was to be held by Power CP in France.

Incredibly the original webpage from 1999 is still online in 2014, and tells a tale of local politicians not allowing the party to be carried out, and forcing a postponement. We have no information leading us to believe it was ever actually held later, and thus we conclude it was cancelled.

There are no links to this party that we can find on other, established demoscene sites.
