can a trustee cite the distribution policy of a plan in the document a

[MJ Hartman]

an employee recently left a company and was provided distribution paperwork on request. after submitting the completed paperwork and a written request for distribution a reply was received citing distributions to terminees only occurred 60 days the close of the plan year in which termination occurred. this would be acceptable except that the owners wife rec'd her full distribution from the plan in aug after terminating from the co. in july. Isn't there something about that if a precendent has been set the trustee/administrator has essentially created a new policy requiring plan amendment/notification? how should the newly terminated employee proceed at this point?
