What Is a Class B Misdemeanor in Wisconsin? 

A Class B misdemeanor is the second-highest misdemeanor classification in Wisconsin. The penalties include a maximum of 90 days in jail, a $1,000 fine, or both. While a conviction does not carry the same weight as a felony, it remains on your criminal record unless expunged and will appear on background checks. 

Even though Class B misdemeanors are considered lesser offenses, they should not be taken lightly. Having a strong legal defense is critical to avoiding harsh penalties and protecting your future.

Defenses for a Class B Misdemeanor

A Class B misdemeanor charge does not guarantee a conviction. Grieve Law builds strategic defenses to challenge the prosecution’s case at every step, starting from your initial court appearance and the preliminary hearing. Our defense strategies include: 

• Unlawful Search or Arrest: If law enforcement violated your constitutional rights by conducting an illegal search or improper arrest, evidence may be ruled inadmissible. 
• Motion Hearings: Pre-trial motions can be used to suppress evidence or dismiss charges based on procedural errors. 
• Lack of Evidence: The prosecution must prove guilt beyond a reasonable doubt. If insufficient evidence exists, charges may be dropped. 
• Negotiating Charge Reductions: Many Class B misdemeanors can be reduced to Class C misdemeanors, lowering penalties and reducing long-term consequences. 

Grieve Law thoroughly analyzes your case to guarantee your rights are protected and the strongest defense strategy is built.
