Under Section 28F(2), where an unauthorised building or structure has been erected on airport premises, the eviction officer's notice must allow the person a period, not being less than seven days but not exceeding how many days, to remove it or show cause?

Section 28F(2) mirrors the standard 7-to-30-day notice band used elsewhere in Chapter VA (also seen in Section 28G(4) for rent/damages orders): a person who has erected an unauthorised building/structure/fixture must be given a period of not less than seven but not exceeding thirty days to either remove it voluntarily or show cause against removal, failing which the eviction officer may order removal at that person's cost, recoverable as an arrear of land revenue. Notably, Section 28F(3) dispenses with even this notice requirement for MOVABLE structures, goods, cattle, or animals unlawfully placed on airport premises - these may be removed WITHOUT NOTICE altogether, a stricter, summary standard reserved for more easily-relocatable unauthorised items.
