chilling effect
Chilling effect. In a legal context, a chilling effect is the inhibition or discouragement of the legitimate exercise of a constitutional right by the threat of legal sanction. The right that is most often described as being suppressed by a chilling effect is the right to free speech. A chilling effect may be caused by legal actions such as the passing of a law, the decision of a court, or the threat of a lawsuit; any legal action that would cause people to hesitate to exercise a legitimate right for fear of legal repercussions.
