3 Restoration of status
(1) If Portobello Park is appropriated for the educational purposes mentioned in section 1(2), but––
(a) it is not used for those purposes within the opportunity period, or
(b) having been used for those purposes, it ceases to be so used,
then subsection (2) applies.
(2) The previous legal and title restrictions apply.
(3) In this section––
“the opportunity period” means the period of 10 years beginning with the date of the appropriation,
“the previous legal and title restrictions” means so much of the law and such of the terms of the disposition as would have applied to Portobello Park at the time set out in subsection (4) and on the assumption set out in subsection (5).
(4) That time is immediately before––
(a) the expiry of the opportunity period or, as the case may be,
(b) the cessation of use.
(5) That assumption is that the appropriation never occurred.
