178.A superior has certain rights and, sometimes, obligations simply by virtue of being the superior. Such rights and obligations run with the superiority and transmit to successors. Parts 3 and 4 of the Act provide for the extinction (with exceptions) of the two principal rights of a superior namely the right to collect feuduty and the right to enforce real burdens. Section 54 is concerned solely with any other rights and obligations a superior might have by virtue of being the superior. Accordingly it extinguishes any other residual rights which a superior might be thought to have. It also extinguishes obligations on the superior, other than the counter-obligations which are expressly saved by sections 25, 28(1)(a) and 60(1)(a). Section 75 (saving for contractual rights) makes it clear that contractual rights and obligations are unaffected.
179.Subsections (2) and (3) are modelled on the equivalent provisions in section 17 and prevent the enforcement (subject to exceptions) of superior's rights and obligations after the appointed date of abolition.
