Among the Internet sites that relate to the Pigford lawsuit are the following:
PBS has background material on the history of black farmers here.
The settlement in the class action suit called for an arbitrator to make decisions with a separate, independent court-appointed monitor to look over the arbitrator's shoulder (no decision power as I understand). Here's the Office of Monitor's website
Here's the National Black Farmer's Association website, with a record of their actions and USDA's response (in more detail than I've provided).
The lawsuit was settled several years ago. In 2004 the time had run and there was a spurt of publicity about it:
The Washington Post did an article
The Environmental Working Group did a study with the black farmers association 2004 report
Carol Estes did a piece stating the side from the black farmer point of view.
The Delta Press did a piece from another side here
In 2007 the House reopened the discussion and EWG did several pieces here in July 2007
and in their EWG July Update on farm bill
Here is the testimony of John Boyd
