Decisione estratta
The hearing defect was cured on appeal and no further fact-finding was needed because the missing materials were not decisive.
Motivazione estratta
The appellants obtained later access to the file, the contested documents were not shown to be outcome-determinative, and the authorities could lawfully rely on the existing record and anticipate that further evidence would not change the result.
