Commentary on Sections Part 6 – Noise Chapter 1: Audible Intruder Alarms Section 51 – Nomination of key-holders
This section (subsections (3) to (5)) describes who is eligible to be nominated as a key-holder. Subsection (6) provides that where a key-holder ceases to satisfy certain requirements, the responsible person must nominate a replacement. The responsible person would then, under section 50, have to notify the details of the new key-holder to the council.  Again, failure either to nominate or notify would be an offence.
