Is there a juristic reason for enrichment and corresponding deprivation?

However, in my view, there was a juristic reason for the enrichment and corresponding deprivation. One of the examples of established juristic reasons noted at paragraph 41 of Kerr v. Baranow, is “where a valid statute denies recovery”. In the case at hand, Section 152, of the Municipal Government Act denies recovery, as part of the redemption price, for repairs made by the purchaser without the written approval of the treasurer. The Applicants are seeking to recover that which the Act denies recovery for.
