An enforcement authority may impose a penalty under section 18 in respect of a breach of a leasehold house restriction which occurs outside that authority's area (as well as in respect of a breach which occurs within that area).
If an enforcement authority ("LA1") proposes to impose a penalty in respect of a breach which occurred in the area of a different enforcement authority ("LA2"), LA1 must notify LA2 that it proposes to do so.
If LA1 notifies LA2 under subsection (2) but does not impose the penalty, LA1 must notify LA2 of that fact.
If an enforcement authority receives a notification under subsection (2), the authority is relieved of its duty under section 17(1) in relation to the breach unless the authority receives a notification under subsection (3).
If an enforcement authority ("LA1") imposes a penalty in respect of a breach which occurred in the area of a different enforcement authority ("LA2"), LA1 must notify LA2 of that fact.
