line judge duties

[WilliamK]

Hi,
First time ever posting question. But have followed forum for along time. Had a weird situation in my daughters VB game over weekend. Daughter plays D-2 VB just happened to be playing host team with their ens soccer players line judging tournament.
1. Our girl prepars to jump serve about 6 or 7 feet behind line
2. line judge steps behind server about 3 or 4 feet about 10 feet from back line
3. girl serves about 2 or 3 volleys go by ref blows whistle
4. line judge is waving flag
5. he says girls crossed line by a 1/4 inch
6. ref awards point to other team we lose 25-23

I have no problem with the line judge calling foot faults, but in that situation should'nt the Up Ref be looking for that infraction. I have a hard time believing the line judge could see that from where he was! If he had said she was over by 3 or 4 inches, but to say he could see 1/4 inch seems a little farfetched to me! If there are any VB refs that can offer some insight to this? Who has this call in this situation or was this handled correctly. Just seemed to have everyone shocked by the 1/4 inch reference when he was about 10 feet behind line!
