A due process principle requiring that laws, regulations, and judicial rules provide clear warning of prohibited or required conduct. The principle ensures that ordinary people receive fair warning of what the law forbids and that enforcement authorities do not exercise unbridled discretion.
Fernando Farrell obtained a $10,000 compensatory verdict against Frontier Capital for a defective product. The jury then returned a $25 million punitive award.

Faith Fitzgerald, counsel for Frostline Textiles, told reporters that her client would vigorously defend a pending suit.

Farid Farahani recovered $100,000 in compensatory damages from Ferrum Metals for bad-faith claims handling. The jury added $25 million in punitive damages.

Francisco Frost filed a securities fraud complaint against Fairview Manufacturing alleging scienter based on internal reports. The court assessed whether the allegations supplied the strong inference required for the claim to proceed. The standard ensured defendants received fair notice of the precise conduct alleged while filtering out insufficiently particularized claims.
