Maybe Mordacai can help resolve this issue, but I don't believe they have a choice regarding the commons. The commons represent an ownership interest. If the company is worth something (assets > debts) then the commons have value. Canceling would be like stealing.
But if the company is not worth something (assets < debts) then the commons lose out. I believe under this scenario, shareholders must lose all before creditors lose any.
So these shares may become worthless during the bankruptcy process, but it's not a choice some lawyer or executive makes.
The following is mordicai's first post on the WMI board. The other one I posted was his post on the Wachovia board on the same date however he does mention WAMU in the other post.

Although this would fall under the category of an emergency seizure to protect the deposits, I would presume there is some kind of post seizure appeal available to WaMu (or now the bankruptcy trustee) to contest the seizure altogether on whatever grounds. I am not saying any such appeal would be made or would be successful --- just that the due process clause dictates some type of hearing if this was just sprung on WaMu without advance warning. Here is a link to the law if anyone is interested in finding a definitive answer.
