When Her Majesty's Most Honourable Privy Council exercises its judicial functions (through the Judicial Committee), Law Lords may make statements that are not technically a part of the decision, but are nonetheless relevant to establish the context of the decision or to explain an area of law. Such comments that are not part of the decision are obiter dictum.
I think you may be confusing the meaning of the term. The word obiter dicta is a Latin word which means "things said by the way." Obiter dicta can be passing comments, opinions or examples provided by a judge. Statements constituting 'obiter dicta' are not binding. [For example, if a court dismisses a case due to lack of jurisdiction and offers opinions on the merits of a case, then these opinions constitute 'obiter dicta.'] Obiter dictum (plural of obiter dicta) is an opinion or a remark made by a judge which does not form a part of the court's decision. Therefore, obiter dictum are not legally binding and can ONLY be rescinded, or withdrawn, by the judge who made them.
Obiter Dicta
Obiter dicta is a remark made by a judge which forms no part of the reasoning that is directly responsible for the verdict (called the 'rationes decidendi" also called simply "the ratio"). When reading a judgment if a statement is essential to the reasoning of the decision it is part of the rationes decidendi. If it is a side comment, superfluous or not connected to the main body of reasoning its called obiter dicta or simply dicta.
Ratio decidendi refers to the legal reasoning behind a court's decision that forms the binding precedent in future cases. Obiter dicta are statements or opinions made by the court that are not essential to the decision and do not create binding precedent, but may provide guidance or insight on the case.
"Obiter dictum" or simply "dictum" or "dicta" is the term used to describe statements made by a court in its opinion that are unnecessary to decide the case. When such an unnecessary statement is used to negate a party's attorney's position, that attorney will refer to it as "merely obiter dictum (or "mere dicta") which does not bind this court." When used in support of the case, it is called "supporting rationale for the court's ultimate decision deserving of great weight for its wisdom."
if dicta is not binding, why is it important?
The word "dicta" is a Latin plural. The singular is dictum.
Dicta Johnson was born on 1887-06-29.
The plural of dictum is dicta, or dictums
Words said in passing in a court case in the UK refer to comments made by the judge or legal professionals (such as barristers or solicitors) that are not central to the main legal arguments being presented. These remarks are not binding as legal precedent but may provide insight into the judge's thinking or help clarify certain points.
Deeds not Words!
Dicta-typing is the ability to type out what is being said accordingly. You should be able to type in a 100% accuracy and have an ear for detail in order to catch everything being said.
