As a retired investment banker I find this whole post funny. As the OP knows, anyone has the right to sue and yes investors have rights and should be protected. However, in this case there are numerous variables at play. Variables that impact value. There are legal liabilities assumed at sale, numerous approvals required (government agencies), strict guidelines for defining a potential purchaser, limited timeframe and a very small pool of qualified buyers. The last two variables are ones that are not discussed much. First, the failure to include the California locations. The Everest schools have no real assets to sell. Buildings are leased as is much of the equipment. However, Heald and Wyo had assets to sale. However, they will move to teach out and/or close. Second, the political component. What are greater needs ... those of investors or students.
OP has a very strong point ... and a potential case. However, there are no other buyers that will be approved. A for profit or equity firm has no chance (read the MOU). The buyers have already prepared for this challenge as well. OP ... keep in mind you will only have a case if you dan prove there are qualified buyers that will get approved.
