PBeM, illegal orders

What do you do when someone issues illegal orders in a PBeM?
I'm thinking about setting stuff up to chop the orders to
what the ship is capable of and going on, sound reasonable?

Admiral:  3 points to Port
Aide:  But Admiral
Admiral:  Give the order!

all the small ships go 3 points to port, leaving the thrust
4 BDN to soak up 12 SMs.
