[CQ-Contest] your opinion pse

[Phillip Conza]

Gentlemen,
                     Your opinions or ideas etc on this please.

A local contester had a contact removed because of :

.Last year an OP  worked a LU station but it was disallowed because he was the only one who worked him, and 4 others had to work it before it was allowed as a multiplier. Nothing in the rules about that - apparently it's accepted international practice. 

I am not on a witch hunt I have read the rules covering this contest and I have read the ARRL DX rules which I take qualify as a body who would use "  accepted international practice " yet I can't find any reference to this ..Is there such or is this pie in the sky ?

Please gentleman your input.. or a pointer to this  " accepted international practice "

Just don't want to see it happen again ..
