I'm not one to use the term "Constitutional crisis" loosely, but if this ruling stands, I think we are at that point. Alsup's decision means federal agencies cannot legally respond to a White House directive to reduce their headcount. It also changes the legal status of probationary and term appointments to tenure rather than how they have been traditionally viewed. IANAL, but I think the ability of the American Federation of Government Employees to intervene on behalf of employees who are not represented by a bargaining unit in an employment matter is highly suspect.
