Questions
What should I do immediately after a DUII arrest in Oregon?
Contact Thompson Law immediately to request a DMV hearing within 10 days. We'll analyze procedural violations, challenge evidence, and develop defense strategies to protect your license and minimize penalties.
Can Ballot Measure 11 mandatory minimum sentences be reduced?
Yes. Our team challenges prosecutorial overreach, explores opt-out provisions, and pursues appellate reversals to avoid or reduce Measure 11 sentences through strategic pretrial motions and trial outcomes.
How does expungement affect background checks in Oregon?
Successful expungement seals official records, making arrests or convictions legally inaccessible to employers, landlords, and licensing boards under Oregon Revised Statutes 137.225.
What differentiates Thompson Law's sex crime defense?
We combine forensic expert collaboration, jury selection strategies, and confidentiality protocols to address sensitive allegations while challenging evidence credibility and prosecutorial narratives.
Can appellate courts overturn jury verdicts?
Yes. We identify trial errors, constitutional violations, and prosecutorial misconduct to secure appellate reversals, as demonstrated in multiple published Oregon Court of Appeals decisions.
