Umpire Obstruction?

[Rog]

For the sake of the original question -
NFHS 2002 Rules Book
page 36
Dead Ball Table
#17
5-5-1-h
Awards or penalties
Runners return to bases they had reach or passed when ball became dead
8-2-6; 5-2-1

Seems pretty cut-n-dried,
no room for any umpire discretionary rulings.....
