Estoppel, Res Judicata and Stare Decisis


COMMENT

'Estoppel' refers to a party being barred from asserting a claimed right because of them having elected, either directly or implicitly, a past position inconsistent with that now-claimed right. Such a 'position' may be taken or made by statement, action - or even inaction. For example, you may be 'estopped' from arguing interpretation A of a contract, when you have relied on the contrary position B for the last year.

In Ryan v. Moore (SCC, 2005) the Supreme Court of Canada lists the six recognized types of estoppel:
52 The jurisprudence discloses six types of estoppel: estoppel by representation of fact, proprietary estoppel, promissory estoppel, estoppel by convention, estoppel by deed and estoppel by negligence (see Bower, at pp. 3-9). ...
Res judicata and stare decisis are similar only they are more authoritative, since the accepted position is 'officially'-endorsed - ie. having resulted from a past legal ruling (res judicata) or from established legal principle (stare decisis). Stare decisis comes in at least two types - 'vertical' and 'horizontal'!.

What all of these doctrines share is that they operate to block arguing against something that is already established - either factually, legally - or both.
