The fifth Estate couldn't even give that information out when contacted. They just said they're being sued, and both "Bad Blood" programs (1976 and 1999 follow-up) are embargoed and apologized for not being able to discuss it.
Great way to muzzle the media, huh? I haven't been able to find where in the court system this is recorded.
We can thank God, BigM got the transcripts from the 1976 show at least.
A poor lawyer can let a case drag on for years, a good one can make it last for decades.
