Legal Question in DUI Law in Wisconsin

WI law does not impose any statewide time limits upon officers to prepare police reports; in fact, there is technically no requirement that such a report ever be prepared for many routine law enforcement activities which do not involve citizen contacts. Realistically, however, most agencies would impose such requirements in the own internal procedures rules (as opposed to statewide laws), which vary from agency to agency, particularly in situations where someone is detained against their will, and it would also be highly unusual for such reports not to be prepared promptly. The "filing" of reports, however, is a vague concept, since different departments within different agencies have their own individual databases where reports might be stored or filed. In agencies which engage in under cover investigations, such locations could be limited to the briefcase of the investigating officer during the time when a confidential investigation remains open. However, most agencies have a central records bureau where reports from the majority of closed investigations would eventually end up, and where they become subject to the WI Open Records law which provides for public access to them.
