Anatomy of a Colorado Opening Brief, and Where They Go Wrong

The opening brief is a structure before it is an argument

An appellate opening brief is one of the few documents in practice whose shape is prescribed. The Colorado Court of Appeals expects particular components, in a particular order, and a brief that omits one or puts it in the wrong place invites a response about form rather than merits.

That prescription is an advantage, and most of the anxiety around appellate drafting comes from treating it as a blank page instead. Below is the anatomy of the document, then the four places where briefs actually go wrong.

The anatomy

A Colorado opening brief assembles from a fixed set of parts:

Case caption. Court, parties, case number, and the designation of the court below.

Table of contents and table of authorities. Generated last, verified against the finished text, and — worth knowing — outside the word count.

Statement of the issues presented. The single most-read part of the brief after the summary. Each issue should be answerable and should carry, at minimum, the standard of review and where the error was preserved.

Statement of the case. Procedural history. What happened in the trial court, in what order, and what is on appeal.

Statement of the facts. Record facts, each cited to the record. Not argument. The discipline of writing this section without adjectives is what makes the argument section credible when it arrives.

Summary of the argument. Short, and written after the argument rather than before it.

Argument, divided by issue. In practice this is where the brief is won: each issue as its own numbered section, each opening with the standard of review, each demonstrating preservation.

Conclusion. The relief sought, stated precisely.

Certificate of compliance and certificate of service.

Every one of these is expected. The argument section is where your judgement lives; the rest is a form you should be able to fill without deliberation, so that your attention goes where it is worth something.

Where briefs actually go wrong

Preservation, asserted rather than shown. An issue not preserved below is reviewed, if at all, for plain error — a far harder standard. The place to establish preservation is in the brief, at the point the issue is raised, with a record citation to the objection or motion where it was made. “This issue was preserved” without a citation is an assertion the court has no reason to accept.

Facts without record citations. A fact section that reads well and cites nothing is worse than one that reads awkwardly and cites everything. Opposing counsel will check. The court will notice which of you did.

The standard of review left implicit. De novo, abuse of discretion, clear error and plain error lead to different outcomes on identical facts. A brief that does not name the standard for each issue has left the most consequential thing in the case for the other side to characterise.

Word count and the certificate. Covered separately in our note on the certificate of compliance, but the short version: the applicable limit does not count the caption, tables, certificates or signature blocks, so the number your word processor reports is not the number the rule is asking about — in either direction.

A method that fits the structure

Work from the record outward. Build the fact section first, with citations, before writing any argument. Arguments written before the facts are assembled tend to describe the case you remember rather than the case in the record.

Draft each issue as a self-contained unit. Standard of review, preservation, the error, the law, why it matters. If an issue cannot survive as a standalone section, it may not be strong enough to include — and a weak issue costs more than it appears to, because it invites the court to read the whole brief more sceptically.

Write the summary last. It is a summary. Written first, it becomes a plan you then feel obliged to follow.

Generate the tables at the very end, and verify them against the finished document rather than a draft. Table entries pointing at pages that moved are a common and avoidable embarrassment.

Leave time for the certificate. It is the last thing drafted, at the moment of least attention, and it is a certification.

What AI can and cannot responsibly do here

It can assemble the parts of the brief that are structural, retrieve record material by citation, and produce first drafts of fact statements attributed to the documents they came from. That is genuine time back, and it is exactly the part of the work that is tedious rather than skilled.

It cannot decide which issues to raise. That judgement — which errors are strong, which are preserved, which are worth the court’s attention — is the appellate lawyer’s actual contribution, and no current system is in a position to make it.

There is also a rule here that has become a filing requirement in some courts and simple prudence everywhere: any authority cited must be verified against a reporter or a traditional database before it goes in. In the District of Colorado, one standing order specifies that method expressly — see our note on AI certification in the District of Colorado. A brief citing a case that does not exist is the one error from which there is no recovery.

How COAPP approaches it

COAPP builds the opening brief as the structure it is: the required sections in order, retrieval over the record you upload, each generated section attributed to the documents it drew from, and formatting and word limits applied as the document is assembled rather than checked at the end.

The attribution is the part we would defend hardest. A generated fact statement that shows you which transcript page it came from can be verified in the time it takes to read one line. One that cannot has simply moved the work to the person who has to check it — which, on an appeal, is you.
