I hope this message finds you well. I am a licensed attorney with over a decade of litigation
experience. It is a pleasure to assist you today.
The party seeking the extension should have entered into the record their reason for the extension of the TRO. The language in Rule 65 relative to this issue is as follows:
(2) Contents; Expiration. Every temporary restraining order issued without notice must state the date and hour it was issued; describe the injury and state why it is irreparable; state why the order was issued without notice; and be promptly filed in the clerk’s office and entered in the record. The order expires at the time after entry–not to exceed 14 days–that the court sets, unless before that time the court, for good cause, extends it for a like period or the adverse party consents to a longer extension. The reasons for an extension must be entered in the record.
The last two sentences are what is applicable here. A petition can be filed by the party seeking the extension with the court and should state the reasons for the extension - which need to reflect "good cause". Good cause is a pretty low legal standard in this context. Basically, they need to give a reason that does not sound absurd on its face.
Let me know if you have any other questions.
