precedentless
Without prior example
Without precedent; having no prior example or established case to follow.
The word appears occasionally in legal and formal contexts where *unprecedented* would be more natural: The court faced a precedentless situation.
Most writers prefer *unprecedented*, making *precedentless* sound slightly awkward or overly constructed.
