I'm using the closest applicable rule per 801.01A. Oversight by RC not to cover throwing from anywhere versus your lie.
I don't think it is an oversight. Throwing from somewhere other than within 30 cm behind a marker – whether by a foot or a hundred feet – is a stance violation. That's different than playing the
wrong lie, where the player is playing from within 30 cm of what he thinks is a marker. Both situations are covered with non-overlapping rules. The closest applicable rule in this case is the actual rule that is applicable.
If the player took the TD to the spot and they found someone else's disc there, then I'd call it a misplay.
Except the OP is not simply an example of players FAILING to verify the lie, it's an example of NOT HAVING THE OPPORTUNITY to check the lie:
If you're keeping score, that's two courtesy violations: advancing beyond the away player (801.04.C) and throwing out of turn (801.05.D).
805.02 Scoring
H. After the scorecard is turned in, the total score as recorded shall stand with no appeal, except for the following circumstances:
1. Penalty throws may be assessed at whatever time the infraction is discovered until the Director declares the tournament officially over or all awards have been distributed.
Good point. I was aware of that, but I was thinking there was no penalty to be assessed, since
801.01 Application of the Rules
B. Players are expected to call a violation when one has clearly occurred. Calls must be made promptly.
So, I was thinking all the courtesy violations and the stance violations were either called at the time or didn't become penalties. Unlike misplays, where the rules explicitly state they can be figured out later.
So, if whatever happened after the card was turned in did result in a penalty, it could be assessed. And, as has been pointed out, if the player did throw from a better place on purpose, the penalty is DQ.
The last time I checked, the marker disc, whether it be the thrown disc or a mini, was a disc that establishes the lie. Feel free to cite the rule that demonstrates that's not the case.
The maker disc
marks the lie. The word used here is "establishes". A thrown disc up in a tree establishes a lie, but does not mark it. A thrown disc that is OB establishes the lie, but the lie is not at the disc.
