Minimum Auction Price (MA, NH)

I'm trying to find the case law in MA and NH that establishes the following condition at an auction: At an foreclosure auction in MA and NH the bank must set a minimum offer of at least 70-75% of fair market price of the property as determined by tax assessment or certified appraisal, etc. I understand from two different sources that during last recession of the 1990's that several cases went to court in NH a case of Murphy vs ???Lender???; and in MA a case of Rubick vs ???Lender??? A MA auctioneer told me that I'd find the information on The Warren Group website, but it looks like I have to pay to join. A NH real estate investor said that the last NH case he was familiar with was in Derry or Londonderry, NH in 1997. Where can I find this and related info? 8-/ [ Edited by JEFFTUSTIN on Date 01/22/2004 ]
