For example the case of Northwood Solihull established that S213 prescribed information certificates from corporate landlords must be executed in line with the companies act. Following this judgment people were able to retroactively apply it to unduly executed certificates that preceded the precedent. If this case precedent later got overturned on appeal following many cases that the earlier verdict's precedent had enabled, can these posterous cases' rulings also be reversed?
In other words, suppose that following Northwood Solihull Alice claims against her landlord ACME Inc under HA2004s214 for improperly executed confirmatory certificate under prescribed information order 2007. She is awarded her s214 claim. Then Northwood Solihull gets overturned on appeal. Is ACME Inc entitled to claim their penalty amount back from Alice (and then what of costs?)
If not, then if a breach occurred after the original Northwood Solihull ruling but before the appellate overturning one, can it still be claimed on after the appellate ruling is given but before its relevant limitation period of 6 years expires?
Why or why not, and isn't this inconsistent?
