Ways of avoiding a binding precedent
Distinguishing
(Binding precedent)
Balfour v Balfour and Merrit v Merrit
(Distinguishing)
Overruling
(Binding precedent)
BRB V Herrington Addis v Dumbreck
(overruling)
In Addie v Dumbreck, the HoL held that occupiers only owed a duty to trespassers to avoid intentional harm, offering minimal protection. In BRB v Herrington, this was overruled, and the court introduced a duty of ‘common humanity’, requiring occupiers to take reasonable care if they know of a danger and the likelihood of a trespasser. This is an example of the House of Lords using its power to overrule a previous decision.
Reversing
(Binding precedent)
Sweet v Parsley
(reversing)
The Court of Appeal convicted a teacher for drug use on her property, but the House of Lords reversed the decision, ruling that mens rea was required for the offence. This is an example of reversing, where a higher court changes the decision of a lower court in the same case.
Tomlinson v Congleton BC (2003)
(reversing)
The Court of Appeal held the council was liable after a man was injured diving into a lake, but the House of Lords reversed the decision, stating he was a trespasser who ignored clear warnings, and the council wasn’t liable. This shows reversing, where a higher court overturns the decision of a lower court in the same case.
Hierarchy of the courts
Every court has to follow the decisions of courts which are above them in the court hierarchy.
London Street Tramways v LCC (1898
-HOL held that certainty in the law was more important than the possibility of individual hardship being caused through having to follow a past decision
-therefore if a bad decision has been made the only way to change it would be a new Act of Parliament
-this rule of precedent became criticised over time and it was argued that allowing the former HOL to change their minds and depart from a previous bad decision would provide justice
