You misread. They are claiming that mail older than 181 days or mail that has been opened falls under the lower standard.
Edit: To your main point, I think your emphasis on the fact there is still a court order is misplaced. Of what practical value is a court order if there is no burden to show probable cause (instead only 'relevance to an ongoing investigation'), and you have no opportunity to challenge (or even know about) the order. How many requests under such a standard do you really think are going to be turned down?
You're right. Thanks! But, I wasn't moved to comment by the 181 day standard or the "opened" standard, both of which are, excuse my bluntness, retarded. The real issue I have is the fact that there's still a court order involved.
