Was there a Republican filibuster in 2000?

Was the attempt to keep Richard Paez from being approved a filibuster?

By every account I can find, most people seem to be calling it that. Here is one example.

However, I’ve rarely seen this mentioned when there is talk of a Democrat filibuster happening in the near future.

Based on what I’ve read, this most certainly was a filibuster.

Was it or wasn’t it?

Apparently yes. (PDF warning.)

Interesting document. However, as the document itself points out, whether or not a filibuster is occurring is hard to know for certain.
