Recordings and NON customer q

Specifically not a Zoom customer but was in a meeting via a court.  I have asked for the recordings for the two meetings from the court but they have taken a meeting that lasted almost 30 min via phone during covid and changed the recording being provided to me a 28 second recording of the baliff saying the named party did not appear.  Can I get the recording from Zoom with a subpeona, if need be?  Ho long would they retain the recording?
