Detecting Omissions from the Document Alone
Can missing controlling or adverse authority be detected by examining a finished brief, without access to the research process that produced it?
Why it matters
Most briefs reach a reviewer, a supervising partner, a court or a carrier as finished documents. If omissions can be found only by rerunning the research, the review that actually happens will keep grading what is present. A method to audit missing authority from the document alone is one of the conditions we named for reconsidering our position on post-hoc verification.
State of the art
Citation verifiers check the existence, support and currency of the citations on the page. By construction, absence has no representation in their input. Human reviewers catch omissions by knowing the field, which does not scale, and which suffers from automation complacency when a checker has already marked the document clean. Some omissions leave traces a careful reader can see: a string cite of district courts that skips the circuit authority above them, an ellipsis that removes a qualifier, an element the brief never analyzes. These are heuristics, not a method.
Our partial answers
The completeness protocol turns completeness from a feeling into an artifact: a frame, an element list and a matrix in which every cell ends in a citation or a logged search, so a blank cell becomes visible. It depends on the process record, not only the document. Its four omission classes (unretrieved authority, unaddressed element, uncited record fact and negative space) say what to look for, and one of them is partly detectable from the document, since the governing law supplies the element list against which a brief can be checked. The opposition design treats the silences of a motion as findings and logs them.
What remains open is the general case: given only a brief and a corpus, estimating, with a measured error rate, which controlling or adverse authorities should have appeared and did not.
