The job was suppose to be a small commercial job with steel studs. The EC drilled 2 small holes in the stud, stuck a tie wrap through the holes and pulled it tight. It held the BX/MC close to the steel stud. He got a failed sticker. My thoughts to him was, Is the tie wraps Listed and labeled for the application? If so, then he should not fail the job. However if they were not listed the AHJ had every right to fail him.

Now comes the all important 90-4 section of the NEC. Should the AHJ fail him for that?
