Overruled?

[Scrapper1]

Is the R1 allowed to overrule the R2 on an overlap call? This happened to me at my last match. I called the rotation fault on the receiving team. R1 calls me over to the stand and says, "They're ok." I tell him that 9 and 4 are opposite and 9 was in front of 4. I knew, but didn't say, that 9 was back center and 4 was front center. (How did I know? I had my wheel! ) The R1 tries to explain to me why they were legal (using his fingers to illustrate), but I didn't really understand what he was saying. So I just said, "So we're not giving the fault?" He said, "Right" and signaled a replay.

After the set, we had an intermission (gee, I love that in a high school match ) and he again tried to explain why there was no rotation fault. He was saying it could only be a fault if she was here and this one was there; and he was using his fingers again.

I listened as patiently as I could and said (as respectfully as I could), "I honestly don't understand most of what you just said. But what I do know is that 9 was back center and she was in front of the front center. I'm positive of that."

Sorry, I didn't mean to rant; but I was very frustrated during this match. So,

1) Is the R1 allowed to make that overrule in the first place?

2) Since I was positive, is there any other way to handle it? I didn't want to have an argument on the court, obviously.
