Why Proper Citation of Appellate Briefs Matters
An appellate brief is not just persuasive writing. It is a formal court filing governed by strict rules. Proper citation shows professionalism and respect for the court. It also makes things easier for the court attorneys and judges to read citations in the style they use when writing decisions.
In New York’s courts, citation format is governed by the New York Law Reports Style Manual, commonly called the Tan Book.
Here is why proper citation matters:
- Credibility: Judges rely on precise citations to verify authority quickly.
- Clarity: Clean legal citation makes your argument easier to follow.
- Compliance: Improper citation can frustrate the court and undermine your advocacy.
A well-cited appellate brief reflects strong legal writing and careful attention to detail.
The Basics of Tan Book Citation
The Tan Book provides rules for citing:
- New York cases
- Federal cases
- Statutes (such as CPLR provisions)
- Regulations
- Court filings and records
Case citations typically include:
- Case name
- Reporter volume
- Reporter abbreviation
- First page
- Court and year (if required)
For example:
Smith v Jones, 25 NY3d 123 (2015)
The Tan Book also sets formatting rules, including:
- Proper abbreviations (e.g., AD3d, NY2d)
- Avoiding unnecessary punctuation
The Tan Book simplifies many citation rules. It is designed specifically for New York courts, and while lawyers are not required to use it, they should.
Step-by-Step Guide to Using the Tan Book in Legal Submissions
If you are citing an appellate brief or related authority, follow these steps:
Step 1: Identify the Authority
Determine whether you are citing:
- A reported case
- An unreported decision
- A statute (e.g., CPLR 5513[a])
- A prior appellate brief
Each has its own citation format.
Step 2: Format the Case Name
Under Tan Book citation rules:
- Use proper abbreviations (e.g., “Co.” instead of “Company”) from the Tan Book’s Table of Authorities.
- Omit first names unless necessary.
Example:
Bray v Cox, 38 NY2d 350 (1976)
Step 3: Add the Reporter Information
Include:
- Volume number
- Reporter abbreviation
- First page
If citing the Appellate Division:
Doe v Roe, 172 AD3d 1127 (2d Dept 2019)
Notice that the department is included for the Apellate Division citations.
Step 4: Cite Statutes Correctly
When citing statutes in an appellate brief:
CPLR 5501(a)
Do not overcomplicate the format. The Tan Book favors clarity and simplicity.
Step 5: Check for Consistency
Consistency in citation format throughout your appellate brief is critical. Law clerks notice inconsistencies immediately.
Step 6: Do Not Use Parallel Citation
CPLR 5529(e) states that only citations to official reports shall be used when citing to New York decisions. This eliminates the Blue Book rule on parallel citations.
Examples of Proper Citations for Motions and Appellate Briefs
Here are sample citations that follow Tan Book citation standards:
Court of Appeals Case:
Rivera v Montefiore Med. Ctr., 28 NY3d 999 (2016)
Appellate Division Case:
Natoli v City of New York, 180 AD3d 477 (1st Dept 2020)
CPLR Statute:
CPLR 5701(a)(2)
Unreported Slip Opinion:
Smith v Jones, 2023 NY Slip Op 01234 (2d Dept 2023)
These examples reflect proper citation format for a New York legal submission.
Common Mistakes in Appellate Brief Citation

- Using Bluebook instead of Tan Book format in New York state courts
- Omitting the department in Appellate Division citations
- Incorrect reporter abbreviations
- Incorrect case name and statutory abbreviations

Another frequent error is over-citation. The Tan Book encourages clear, concise legal citation—not clutter.
Before filing your appellate brief or motion, review every citation carefully. Accuracy matters.
