Errr yeah, I know the laws says that a face down lead is a lead. What I am trying to ascertain is why does this law exist, why shouldn't I put the card back it my hand and lead another card?
That's different. If that is your question then this is the wrong forum. No wonder I have misunderstood you.
Mind you, I cannot see any advantage to being allowed to change your lead anyway.
