UIC interference

[Dutch Alex]

The following happened to me last Saturday and I'm more than angry!

Bases ampty, outs of none importance. A long, hard hit into right field. Got stuck at the fence. Got it stock? I don't know! F9 stands with the arms in the air, as a signal that the ball got stuck. Just before I, as BU, can kill the play and go over there to look at the ball an optic-yellow ball is thrown into the diamond.
I look again, it was really F9 throwing the ball! B-R was on her way to 3th base as F9 was standing with the arms up.
My instant thought was and is, let the runner stay on 3th; not sending her back to 2nd. We have an agreement: "Pick it up, then you play on. Let it lay on the ground, BU will come over to have a look!"

How ever, as I gave the signal that the runner will stay on base 3 our National IUC stepped in. He spoke to my PU. As I noticed it and I wasn't invited; I rushed over. At that point their conversation was over. The PU ordered the runner back to 2nd base.
As I asked what the F... was going on, PU informed me that UIC instructed him that way. He, the PU, killed the play by signal -not verbal-. I didn't see (nor hear) that! So runner has to go back to 2nd...

Did anyone had this unappropriated / unexpected / unwanted kind of misbehavior happened to him before? How did you handle this? What could I do [then and now]? -note: we work this union, or we work not / The Neth.'s have only one union-
