What Does 'Stare Decisis' Mean and Why Is It Important?

The Principle of 'Stare Decisis' Requires a Judge to Make Decisions By Following Similar Reasoning As Within Past Cases Involving Similar Legal Issues.

Generic Lawsuit Document The actual Latin translation of stare decisis is, "To stand by that which is decided", and although an inaccurate translation from the literal Latin, the principle of 'stare decisis' may be thought of as the starring precedent setting decision when a judge is reviewing a set of facts and looking to case law of similar cases in the past for guidance on how to rule in the current situation.  The principle of stare decisis is to provide parties within legal proceedings as well as the advocates and the judges and adjudicators with an opportunity to rely upon guiding precedent.  Guiding precedent establishes a baseline understanding of what should be anticipated and thereby provides some assurance of predictability and consistency with the law and what should be expected as 'justice'.

What Should Happen When a Similar Case Was Decided In the Same Level of Court? Does Stare Decisis Apply?

A Judge Should Apply the Stare Decisis Principle Unless a Strong Reason to the Contrary Exists So to Ensure Predictability and Consistency Within the Law.

It is generally well understood, even if understood without awareness of the term stare decisis, that lower courts are required to follow judicial decisions from higher courts.  This very basic principle is taught in introductory law classes at high schools; however, it can be troublesome, even for legal professionals and the courts themselves, to fully understand whether courts should follow prior decisions from courts of the same level.  Per the case of Whitford v. Backman, 2016 CanLII 1308 it appears that a strong argument exists to argue that a Judge in a lower court should, for consistency and predictability purposes, follow previous decisions of a Judge who handled a similar case in the past and do so even though the Judge in the past case was sitting in a court of the same level.  In Whitford, a Judge within the Small Claims Court specifically stated that:

Given this analysis by a court of co-ordinate jurisdiction, the issue before me is whether the doctrine of stare decisis applies.  Some courts have held that there can be no stare decisis between judges of the same court only a question of collegiality. However, there is ample authority that stare decisis is a doctrine to be considered by courts of co-ordinate jurisdiction.  The obvious rationale for respecting decisions of courts of co-ordinate jurisdiction is that “[i]t is undesirable that a judge sit on appeal from a decision of a judge of co-ordinate authority.  To permit such a practice would foster inconsistency and uncertainty respecting decisions made by the same court.”  In Wolverine v. R., Wimmer J.  stated:

It is true that the doctrine of stare decisis does not absolutely bind a judge of first instance to follow a prior decision of another judge of the same court, but a failure to do so is a disservice to litigants, lawyers and inferior courts who are entitled to see the law as reasonably settled and certain.  It is for courts of appeal, not individual judges of equal jurisdiction, to correct judicial errors.

There are only very limited circumstances where stare decisis would not be binding on a court of co-ordinate jurisdiction.  In Burroughsford v. Lynch, Goodfellow J.  set out the exceptional circumstances.  Goodfellow J.  stated:

Generally one is bound by the decision of another Justice of the Court when the subject-matter is substantially indistinguishable.  I am not bound by any statute or provision in the Judicature Act, R.S.N.S.  1989, c.  240; however, in the interests of predictability and certainty, one should usually follow the decision of another Justice unless one is convinced that the judgment is wrong or there exists strong reason to the contrary.  Strong reason to the contrary might be something that indicates the prior decision was given without consideration of a statute or some authority that ought to have been followed, and not simply a strongly held contrary view by the second Justice.  One obvious consideration for not being bound by a fellow Justice’s decision is subsequent direction, comment or overruling of that decision by appellate courts.

Goodfellow J.  was affirmed by a unanimous Nova Scotia Court of Appeal both as to “the result reached and, in general, for the reasons he gave.”[9] Similar wording for the test of “strong reason to the contrary” is stated in R.  v. Northern Electric Co., a decision favoured by the courts, but not referred to in Burroughsford.  McRuer C.J.H.C.  stated:

I think that “strong reason to the contrary” does not mean a strong argumentative reason appealing to the particular judge, but something that may indicate that the prior decision was given without consideration of a statute or some authority that ought to have been followed.  I do not think “strong reason to the contrary” is to be construed according to the flexibility of the mind of the particular judge.

The test of “strong reason to the contrary” is similar to the per incuriam exception to stare decisis.  The phrase “per incuriam” literally means “through lack of care.” It refers to a judgment of a court decided without reference to an earlier judgment which is relevant or to a statutory authority which is binding.  The court’s attention must be drawn to the relevant authorities.  A decision made per incuriam is not binding on courts of co-ordinate jurisdiction.  A leading decision is David Polowin Real Estate Ltd.  v. The Dominion of Canada General Insurance Co. Laskin J.A., for the court, a five-member panel, stated:

[111] The insurers rely on the per incuriam exception to stare decisis.  This well-recognized exception permits a court to overrule one of its previous decisions if two conditions are met: the panel deciding the earlier case did not advert to judicial or statutory authority binding on it; and had the panel considered this authority, it would have decided the case differently: see Al’s Steak House and Tavern Inc.  v. Deloitte & Touche, (1997), 1997 CanLII 2339 (ON CA), 13 C.P.C.  (4th) 90 (C.A.); Metro.  Toronto v. L.J.  McGuinness & Co.  Ltd., 1960 CanLII 165 (ON CA), [1960] O.R.  267 (C.A.); Morelle Ltd.  v. Wakeling, [1955] 1 All E.R.  708, at p.  718.

Accordingly, it appears that the principle of stare decisis should be applied even with cases involving courts of co-ordinate jurisdiction.  The exception of course would be where a case is available from a higher court or where the prior case from co-ordinate jurisdiction contains reasoning with a "strong reason to the contrary" and should be ignored.

Summary Comment

The stare decisis principle should be applied within judicial decisions even when the prior decision is from a court of co-ordinate jurisdiction, meaning a court at the same level, unless there is an over-ruling higher court decision or the decision from the co-ordinate level is obviously flawed and contains good reason to vary from the prior reasoning.
