Wisconsin has no exemption list. It has the balancing test.
Most states hand their records custodians a menu of statutory exemptions. Wisconsin hands them a presumption of complete public access and, for most contested records, a case by case balancing test. And when a denial is challenged, the reviewing court reads only the reasons the custodian actually wrote down. That changes how a denial letter has to be written.
- The presumption
- The law is construed in every instance with a presumption of complete public access; only in an exceptional case may access be denied (Wis. Stat. 19.31)
- Three categories
- Absolute right of access, absolute denial of access, or access determined by the balancing test (Hathaway, 1984, per DOJ PRL Guide p. 20)
- The balancing test
- Case by case weighing of the strong policy favoring disclosure against any even stronger policy favoring nondisclosure; no blanket exemptions (Hempel, 2005 WI 120, per guide pp. 20-21)
- Mandamus review
- The court examines only the reasons stated in the denial; insufficient stated reasons and the writ issues (guide pp. 17-18, citing MacIver Inst., 2014 WI App 49, and Osborn, 2002 WI 83)
- Denial mechanics
- Respond as soon as practicable and without delay; written request denied means written reasons plus the mandatory review-rights statement (Wis. Stat. 19.35(4)(a)-(b))
The presumption comes first, and it is written into the statute
Wisconsin’s Public Records Law opens with a declaration of policy that does real work. All persons are entitled to “the greatest possible information regarding the affairs of government,” and the statutes are to be construed “in every instance with a presumption of complete public access” (Wis. Stat. 19.31). Then comes the sentence every Wisconsin records custodian should be able to recite: the denial of public access “generally is contrary to the public interest, and only in an exceptional case may access be denied.”
Notice what is missing. There is no list of twenty-odd enumerated exemptions to scan for a match, the way a Michigan FOIA coordinator scans MCL 15.243. Wisconsin built a different machine. The starting point is disclosure, the exceptional case is denial, and the question of which records fall into that exceptional case is answered, for most records, by a weighing exercise the custodian performs personally, request by request.
Three categories, and most contested records land in the third
The Wisconsin DOJ’s Public Records Law Compliance Guide lays out the architecture (pp. 20-21). Every requested record falls into one of three categories, a framework from Hathaway v. Joint School District No. 1 of Green Bay (1984): (1) absolute right of access, (2) absolute denial of access, and (3) right of access determined by the balancing test. Some statutes compel disclosure; some statutes and court decisions flatly prohibit it. Everything else, which in practice is most of what lands on a clerk’s desk, goes to category three.
For that third category, the guide states the rule from Hempel v. City of Baraboo, 2005 WI 120: if neither a statute nor case law requires disclosure or creates an exception, the records custodian must decide whether the strong public policy favoring disclosure is overcome by some even stronger public policy favoring limited access or nondisclosure. The analysis is fact-specific and performed case by case. And the guide is explicit about the corollary: an authority cannot unilaterally implement a policy creating a blanket exemption from the public records law. “We never release personnel files” is not a rule Wisconsin lets an office write for itself.
The guide distills the analysis into a four-step approach (pp. 21-22). Step one: is there such a record? If none exists, the analysis stops. Step two: is the requester entitled to access under a statute or court decision? If yes, access is permitted. Step three: is the requester prohibited from access under a statute or court decision? If yes, access is denied. Step four: does the balancing test weigh in favor of prohibiting access? Only a yes at step four supports denial; otherwise the record goes out.
On review, the court reads only your letter
Here is the fact that should shape every Wisconsin denial before it is signed. A denied requester’s route to enforcement is a mandamus action under Wis. Stat. 19.37(1), and on mandamus review the court examines the sufficiency of the reasons stated for denying the request. Per the DOJ guide’s discussion (pp. 17-18, citing MacIver Inst., 2014 WI App 49, and Osborn v. Board of Regents, 2002 WI 83), it is not the court’s role to hypothesize or consider reasons the custodian did not assert. If the custodian failed to state sufficient reasons, the court will issue a writ of mandamus compelling disclosure, even if a sound but unstated reason existed.
In other words, the denial letter is the case. There is no second chance to brief the real rationale after litigation starts. The guide adds that factual support for the custodian’s reasoning in the statement of denial will likely strengthen the custodian’s position before the reviewing court. A Wisconsin denial is not correspondence; it is the entire record the authority will stand on.
One adjacent trap worth knowing: per the guide (p. 17), an offer of compliance conditioned on unauthorized costs and terms itself constitutes a denial. An inflated fee demand is not a middle path; it puts the authority in the same posture as a refusal. The fee rules have their own structure, covered in our guide to Wisconsin public records fees.
Denial mechanics under 19.35(4)
The statute fixes the procedure. On any request, the authority must, “as soon as practicable and without delay,” either fill the request or notify the requester of its determination to deny in whole or in part and the reasons therefor (Wis. Stat. 19.35(4)(a)). Wisconsin sets no fixed day count for this; how the timing standard actually operates is covered in our guide to Wisconsin response timing.
Form follows the form of the request. An oral request may be denied orally, unless the requester demands a written statement of the reasons within 5 business days of the oral denial (Wis. Stat. 19.35(4)(b)). A written request denied in whole or in part entitles the requester to a written statement of the reasons. And every written denial must carry the review-rights statement: it must inform the requester that if the request was made in writing, the determination is subject to review by mandamus under Wis. Stat. 19.37(1) or upon application to the attorney general or a district attorney. A denial letter missing that sentence is defective on its face.
A related timing rule sits in Wis. Stat. 19.35(1)(h): a request may be made orally, but it must be in writing before an enforcement action is commenced under 19.37. So the written request, the written denial, and the mandamus petition form one paper chain, and the authority’s contribution to that chain is the letter it chose to write.
Who is asking, and why, mostly cannot matter
Wisconsin also strips away the screening questions offices in other states sometimes lean on. A request may not be refused because the person is unwilling to be identified or to state the purpose of the request (Wis. Stat. 19.35(1)(i)). The exceptions are narrow: identification may be required when the requested record is kept at a private residence, or where security reasons or federal law or regulations require it. And the door is wide: a “requester” is any person, except a committed or incarcerated person, who in turn may still request records that specifically reference them, subject to the statute’s conditions (Wis. Stat. 19.32(3)). There is no residency test.
One refinement, attributed where it belongs: the DOJ guide notes (p. 13) that while identity and purpose cannot be demanded, they can still become relevant inside the balancing test. The requester’s identity may bear on a safety concern that outweighs the presumption of disclosure, and the Wisconsin Supreme Court has found the purpose of a request relevant to the balance. The custodian cannot ask; but what the custodian already knows may lawfully carry weight, case by case.
How to write a denial that survives
Put the architecture and the mandamus rule together and the shape of a defensible Wisconsin denial writes itself:
- Name the record. Say what was requested and what exists. If no responsive record exists, the guide says the response should say so.
- State the specific public policy reasons, not just a statute number. If a statute or court decision controls, cite it and explain how it applies. If the denial rests on the balancing test, write out the policy interests weighed and why nondisclosure prevailed in this exceptional case. The reasons on the page are the only reasons a court will consider.
- Identify what is withheld, and release the rest. Per the guide (p. 18, citing Wis. Stat. 19.36(6)), if part of the record is disclosable, that part must be disclosed, and the burden of redacting is not an excuse. Withheld portions should be identified with enough detail for the requester to understand what is being kept back. If redaction cannot cure the problem, say why.
- Include the review-rights statement required by Wis. Stat. 19.35(4)(b), verbatim in substance: mandamus under 19.37(1), or application to the district attorney or attorney general.
- Keep the file. The request, the letter, and the facts supporting the stated reasons are the record the authority will rely on if the requester files. Note that responses to records requests are themselves records.
The discipline is different from an exemption-list state, but it is learnable. The office that treats every denial letter as a short brief, because in Wisconsin it is one, rarely meets a judge over it.

Common questions
Can we just cite an exemption number in a Wisconsin records denial?
No. Wisconsin has no general exemption list to cite. The DOJ Public Records Law Compliance Guide explains that the specificity requirement exists to give adequate notice of the basis for denial and to ensure the custodian actually exercised judgment, and, in the open-meetings-exemption context, that the requirement is not met by mere citation to the exemption statute or a bald assertion that release is not in the public interest (guide p. 17). A denial resting on the balancing test must state the specific public policy reasons for withholding, because those stated reasons are what a reviewing court will evaluate.
Does the requester have to tell us why they want the records?
No. A request may not be refused because the person is unwilling to be identified or to state the purpose of the request, outside narrow exceptions such as records kept at a private residence or where security reasons or federal law require identification (Wis. Stat. 19.35(1)(i)). A requester is any person except a committed or incarcerated person, subject to a narrow carve-out for records about that person (Wis. Stat. 19.32(3)). But the DOJ guide notes that identity and purpose can still become relevant inside the balancing test, for example where a safety concern outweighs the presumption of disclosure (guide p. 13).
What happens if our stated reasons were thin?
The requester loses nothing and the authority loses the case. On mandamus review, the court examines the sufficiency of the reasons stated for denying the request; it is not the court’s role to hypothesize or consider reasons the custodian did not assert. If the custodian fails to state sufficient reasons, the court will issue a writ of mandamus compelling disclosure (DOJ PRL Guide pp. 17-18, citing MacIver Inst., 2014 WI App 49, and Osborn v. Board of Regents, 2002 WI 83). Sound reasons that were never written into the denial cannot rescue it later.
Does a Wisconsin denial have to be in writing?
It depends on the request. An oral request may be denied orally, unless the requester demands a written statement of the reasons within 5 business days of the oral denial (Wis. Stat. 19.35(4)(b)). A written request denied in whole or in part requires a written statement of the reasons. And every written denial must inform the requester that, if the request was made in writing, the determination is subject to review by mandamus under Wis. Stat. 19.37(1) or upon application to the attorney general or a district attorney.
