I think the players should be informed of deviations from the RAW and should give their consent.
Should the players be informed of the class abilities, magic items, templates, Divine Powers, Hit Points, Saving Throws, Spell Resistance, movement rate, bank account size, and otherworldly allies that might by RAW allow an NPC to do something that might very well seem otherwise RAW-impossible?
How are the players to tell the difference between that which is RAW-but-seems-impossible and something that's not RAW unless they know everything the DM knows?
And what's the point of playing if you won't allow the DM to run his world without nosing in on everything?

Crothian,
It would be easier on us if you would provide a standard definition of "DM fiat". For all any of us know, these could be the definitions we're currently arguing over:
"DM fiat means the DM decides what the players know and don't know, and thus is empowered to tell them when what they attempt succeeds or fails, regardless of what the players believe should have happened."
"DM fiat means the DM is allowed to change any rule without prior consideration, notification, or consistency."
The implications of the two definitions will render many and varied opinions; two people who don't disagree on how a DM should act might disagree in this thread because of the lack of a standard definition of "DM Fiat".
