Legal Research Guide: About Case Law

The common law doctrine of precedent is premised upon the hierarchical structure of the court system.
This means that an understanding of the different elements of the hierarchy and how they relate to each other is an important component of case law research.

In Australia, there is a court hierarchy for each element of the federal system.
Each state and territory has its own court hierarchy.
Each of these courts deal with matters that arise out of the state or territorial jurisdiction, as well as some federal matters conferred by Commonwealth statute.
Federal courts have their own court hierarchy and deal with matters arising out of Commonwealth or national scheme legislation (section 77(iii) Commonwealth Constitution, and the Judiciary Act 1903 (Cth)).

Tribunals, such as the Administrative Appeals Tribunal (Cth) and the State Administrative Tribunal (WA) are not courts, but provide a 'quasi-judicial' function and have the task of making decisions in disputes.
Appeals from tribunals to courts are binding and tribunals must follow the precedent of the court decision.

The diagram below shows an outline of the Australian courts and tribunals hierarchy.

Understanding the structure of a case enables you to:

• locate a case
• locate and assess other relevant information that will assist in determining its relevance to a particular situation
• locate similar cases of relevance

Note the structure of the Commonwealth Law Reports version of the Spriggs v Commissioner of Taxation (2009) 239 CLR 1; [2009] HCA 22 case.

Note the use of cur ad vult.
This is an abbreviation for the Latin curia advisari vult, meaning

the court wishes to be advised; the court wishes to consider its decision.
Used in law reports to signify that the judgment was not delivered immediately.

 Law reports are the written judgments of courts on cases which raise significant points of law or expand upon the current understanding of the law

Since the late 1990s unreported judgments are available for most jurisdictions

Law reports are published for the purpose of being used as precedents, providing consistency in the development of common law by ensuring that like cases are decided in the same manner

Law reports may relate to a particular jurisdiction or to a particular area of law, with almost all reported cases being heard in superior courts (all High Court of Australia decisions are reported)

For example, the Commonwealth Law Reports only report cases decided in the High Court of Australia, while the Federal Law Reports cover cases decided in courts of federal jurisdiction, other than the High Court

Reported Judgments

Authorised Reports

Authorised or official reports are those selected and approved by the judiciary, their nominees, or relevant governments department, containing cases which enunciate a general principle or point of law

An authorised report should always be cited in preference to an unauthorised report, (Rules of the Supreme Court 1971 (WA) 0.34.5.9A)

Unauthorised Reports

Unauthorised series of reports are produced quickly and many are directed towards satisfying the needs of specialist practitioners

Unauthorised series of reports include many reports of cases which may be published later in an authorised series, however they also include reports which may only be of transient interest, or illustrate the application of authoritative cases

Law Reports Generally

Few series are mutually exclusive: cases may appear in several series depending on editorial interest and assessment of the importance of the case.
 For example, significant High Court decisions are reported in the Commonwealth Law Reports (CLR), Australian Law Reports (ALR) and Australian Law Journal Reports (ALJR)

• The ALR and ALJR are unauthorised series and the CLR authorised
• The Authorised Report Series is a list of authorised reports of various jurisdictions

Unreported Judgments

When decisions are handed down by a judge or judges they are described as being unreported, thus all judgments start their life as being unreported

Decisions are then selected by the judge or judicial editorial board to be reported in the authorised series, or by publishers for reporting in one of the subject series of reports

Although there is debate about the precedent value of unreported decisions, they are heavily used as they may contain the only statement of the law on a particular subject

Unreported judgments have different citation rules to law reports.

Consideration of Cases

When looking at judicial consideration, cases may be Applied by, Considered by, Distinguished, etc.

How to Read a Case

Orin Kerr,  ‘How to read a legal opinion: a guide for new law students’ (2007) 11 The Green Bag 51

A series of court reports officially approved by the judiciary or government is known as an authorised or official series of reports.

In each jurisdiction only one series is designated as authorised.

Cases which enunciate a general principle or point of law are usually included in the authorised series of reports.

The Law Report Series had several title variations between 1866 and 1891.

Since 1891 the following have been established as the current Law Reports Series:

AGLC Rule 2.2.2 Law Report Series Hierarchy

The authorised version of the report should always be used where available.

The version of a case to be cited should follow the preference order below (from top to bottom):

Reported Cases

The essence of a case citation for a report series is:

Parties' names + year + volume (if any) + series abbreviation + starting page number + pinpoint reference.

Unreported Cases

The essence of a case citation for an unreported judgment in medium neutral format is:

Parties' names + [Year of publication] + Unique court identifier + Judgment no. + [Pinpoint.]

Medium neutral citations are official citations designated by courts, so you can source the case regardless of the publisher/court reporting series.

Each court has an identifier and within each year each judgment is given a running number.
Each paragraph within the case is numbered which increases precision in pinpoint citation within a decision.

Examples:

Singh v Commonwealth of Australia [2004] HCA 43.
Justelle Nominees Pty Ltd v Martin [No 2] [2009] WASC 15, [10].

Consult the AGLC Referencing Guide for more specific citation guidelines.

[Square Brackets] and (Parenthenses)

(Parentheses) are used to include the year when a reporting series numbered its volumes starting a 1 (so you would have no idea of the age of the case without this extra information).

[Square Brackets] are used for reporting series that number volumes according to the year.

Explanation In Detail

With a few exceptions, the choice of [square brackets] or (parentheses) indicates the manner in which the case series is organised.

Where a law report series uses continuous numbering of its volumes, parentheses are used around the year.

Where there is no volume numbering or the numbering begins from 1 again each year, the year is placed in square brackets.
This places the emphasis on the year for location purposes rather than on a recurring volume number.

Some exceptions to this occur in particular case series where the publisher has chosen not to adhere to standard conventions.
For example:  Corbett v Pallas [1995] Aust Torts Reports 62,236.

For more information on the use of [square brackets] versus (parentheses) see 2.2 of the Australian Guide to Legal Citation.

Legal Abbreviations

The abbreviation for a series of law reports is usually the initial letters of the words in the title. 

Case law and journal citations are made up of the abbreviation for the case report series or journal.
Find the unabbreviated case report series or journal title from:

Case Citators

A case citator is an incredibly useful tool to use for legal research. Case citators are a type of case law index.

Case citators can be useful in helping you determine:

• The correct citation for a case;
• If the case has been reported in more than one series of case reports (parallel citations);
• If the case has been reported in an authorised law report series;
• Whether any later cases have considered the case;
• What earlier cases were considered by the case;
• If the case considered any legislation;
• If journal articles have considered the case;
• If the case is still considered good law.

 Students of Murdoch University have access to a number of case citators. For example, Australian Citators include:

• CaseBase in Lexis Advance  
• Digest on Westlaw Australia 
• LawCite (More information)
• AustLII NoteUp
• JADE Citator Search from BarNet Jade (Help for Jade)
  • Jade Professional has extra visualisations and tools
  • Murdoch School of Law students can apply for access:
    • Subscribe to Jade Professional 
      • use your Murdoch student email address

Many of the online case citators also provide a case digest feature which provides a summary of the main points of the case. A popular example of this feature is Digest on Westlaw Australia.

More help with how to use these citators can be found in the help articles linked, in the help section within each database, or within the Online Lessons for Law & Legal Studies Students.

Once you have located a case, an additional component of legal research can be to find cases that judicially consider the case (or parts of the decision) and journal articles that discuss the case.
Where the case is interpreted or discussed in a court, this is referred to as judicial consideration.
The subsequent discussion of a case in other decisions is evidence of the operation of the doctrine of precedent.
Textbooks and commentary often also provide a valuable discussion of case law where it is relevant to the subject of the textbook or commentary.

The  Case Law Lesson shows in detail how to locate cases, legal encyclopaedias and commentary that are relevant to a particular piece of legislation.

You can use AustLII, Jade, CCH IntelliConnect , LawCite, Lexis Advance CaseBase , Westlaw Australia  and a number of other case law databases to find cases that judicially consider a particular case.

When looking at judicial consideration, cases may be Applied by, Considered by, Distinguished, etc.

Court Annotations

The following is list of annotations used by the court in the subsequent appeal proceedings or in the subsequent case where the primary case has been judicially considered.

• Applied A principle of law articulated in the primary case is applied to a new set of facts by the court in the subsequent case.
• Approved The court in the subsequent case has approved the way the court in the primary case, being a court of inferior jurisdiction, has articulated a principle of law.
• Cited The primary case is merely cited by the court in the subsequent case, without comment.
• Considered The legal principles articulated in the primary case are considered or discussed without adverse reflection in the subsequent case.
• Disapproved The decision in the primary case is criticised by the court in the subsequent case.
• Distinguished The court in the subsequent case holds that the legal principles articulated by the primary case (usually otherwise persuasive or binding authority) do not apply because of some essential difference between the two cases in fact or law.
• Explained The decision reached in the primary case is justified by the court in the subsequent case, drawing attention to some feature of the primary case that may not be immediately obvious on its face.
• Followed This annotation is similar to ‘applied’, but is used in circumstances where the facts in the primary case resemble reasonably closely the facts in the subsequent consideration case.
• Not followed The court in the subsequent case has declined to apply the principles of law articulated in the primary case.
• Overruled The legal principles articulated in the primary case are held to be incorrect by the court in the subsequent case, which is a court of superior or equivalent jurisdiction.
• Questioned The court in the subsequent case has expressed doubt about the decision in the primary case, but does not actually determine that the principles of law in the primary case are incorrect.

The Appeal proceedings section of the CaseBase entry has the following annotations used by the courts:

• Affirmed The decision in the primary case is upheld on appeal.
• Reversed The decision in the primary case is overturned on appeal.
• See The decision in the subsequent case relates in some way to the primary case, but the court in the subsequent case is not assessing the merits of the related primary decision.
• Varied The decision in the primary case is only partly reversed or partly affirmed by the subsequent case. It is particularly used in circumstances where the court in the subsequent case has altered the quantum of damages awarded or the sentence imposed in the primary case.
• Related The decision in the subsequent case relates in some way to the primary case, but the court in the primary case is not assessing the merits of the earlier related decision.
• Special Leave Granted Special leave to appeal the decision in the primary case to the High Court or Privy Council has been granted. There is, therefore, an opportunity for the case itself to be overturned.
• Special Leave Refused Special leave to appeal the decision in the primary case to the High Court or Privy Council has been refused. Therefore, the case is considered good law.

What do the colours mean?

The colours merely highlight and draw attention to the particular types of treatment.
They do not change or add to the meaning of the annotation.

• Positive treatments are coloured green. e.g. followed, applied, approved or affirmed
• Treatments indicating caution required are coloured amber. This can be everything from a distinguishing or explaining treatment (indicating that the law is still good but does not apply in the circumstances), to a varying treatment to a questioning (sometimes called a 'doubting') treatment.
• Negative treatments are coloured red. e.g. disapproved, not followed, overruled or reversed
• Neutral treatments are coloured black. e.g. considered or cited

Brackets

In an Australian case citation, the year can be enclosed by either (round) or [square] brackets.

Round Brackets

Round brackets are used when the year is not an essential component of the citation.
This is when a case can be identified by a volume number alone.
For example:

Byrne v Australian Airlines Ltd (1995) 185 CLR 410 

The Commonwealth Law Reports ('CLR') volumes are numbers sequentially, from number 1 onwards.
This volume number is only used once, and is thus unique, so the case can be found without reference to a year.
So the year is not necessary to identify the correct volume.
Cases reported in a volume are not necessarily from one year - they can span years, depending on th enumber of cases reported. 
For example:  volume 172 contains cases from 1991, volume 173 contains cases from 1991-1992, as does volume 174.

Square Brackets

Square brackets are used when the year is an essential component of the citation.
For example: 

Byrne v Australian Airlines Ltd [1995] HCA 24

Square brackets are regularly seen in unreported judgments.

See AGLC Rule 2.2.1 for further explanation.

Parallel Citations

Court reporting is a business.

It is like reporting the news - how a news item is reported by the ABC or SBS, compared with 7, 9, or 10 – how there are different versions which emphasise different aspects.

Case reporting series are similar, in that there are different versions of a case.

If a subject specialist series reports a case, there will be an emphasis on that subject with a lot more detail.

Additionally, the subject specialist and generalist reporting series are available the day following the judgment.

Authorised versions are only available annually.

There is one authorised case reporting per jurisdiction.

References to cases in your textbooks include all of the court reporting series where the case can be sourced.

Listing all case reporting series in which a case can be sourced is called giving parallel citations.

All versions are given because readers may have access to only case reporting series.

Parallel citations are listed as a hierarchy, from the most authoritative down.

You should always attempt the most authoritative case reporting service available.

When referencing or citing a case in your assignments, you should only include the citation of the version you have accessed – not all of the parallel citations.

e.g. Hot Holdings Pty Ltd v Creasy (1996) 185 CLR 149.

Source, and cite, the most authoritative version of a case.
