Surveillances Devices Act 2007, s.7(3):
Subsection (1) (b) [the general prohibition against recording private conversations] does not apply to the use of a listening device by a party to a private conversation if:
. . . (b) a principal party to the conversation consents to the listening device being so used and the recording of the conversation:
(i) is reasonably necessary for the protection of the lawful interests of that principal party
I suggest Jubelin had reason to believe he would be the subject of a complaint by PS and therefore needed a reliable record of their interactions.
Perhaps he also made some recordings for his own reference in decision-making in relation to the investigation re William:
. . . , or
(ii) is not made for the purpose of communicating or publishing the conversation, or a report of the conversation, to persons who are not parties to the conversation.
