The law is deeply suspicious of the argument that a person did something because that is the kind of person they are. Character evidence is the usual name for it, and the rules keep it out of most cases. Habit is the narrow, welcome exception.
Texas Rule of Evidence 406 says evidence of a person’s habit, or an organization’s routine practice, may be admitted to prove that on a particular occasion the person or organization acted in accordance with it. Not their character. Their habit — the specific, regular, almost automatic response to a specific, repeated situation.
The line between character and habit is the whole game. “He is a careful man” is character, and it stays out. “Every workday for eleven years he stopped at that corner, looked both ways, and crossed only on the signal” is habit, and it comes in. Character is a general disposition. Habit is a particular behavior, repeated so consistently that it has gone reflexive. The more specific the conduct and the more regular the repetition, the closer you are to habit.
The rule reaches organizations too, through routine practice. How a company always logs a delivery, always inspects a rig before a shift, always closes out a work order the same way. Proof that the routine truly existed is proof of what almost certainly happened on the one day nobody specifically remembers.
And Rule 406 is generous about how it gets in. The court may admit the evidence regardless of whether it is corroborated and regardless of whether there was an eyewitness. The habit itself, once proven, is enough to support the inference that the person followed it again on the occasion in question.
So the word to carry is habit. It is the one clean road around the wall the law builds against character evidence, and it opens only for behavior specific enough and regular enough to be called automatic. Prove the pattern, and the single occasion proves itself.
See Texas Rule of Evidence 406: evidence of a person’s habit or an organization’s routine practice may be admitted to prove the person or organization acted in accordance with it on a particular occasion, and the court may admit it regardless of whether it is corroborated or whether there was an eyewitness. Compare Rule 404 (character evidence generally not admissible to prove conduct on a particular occasion). This is general information, not legal advice.
