A topic from AEG's L5R CCG Rules forum, copied for Oracle of the Void from a copy of the forum saved in October 2015, so pages it didn't save are missing. Players' names are left out; the rules officials are named. Rulings are as they stood on these dates; later rulings, the rulebooks and the Rules Archive may differ.
Regarding this
I think Lies, Lies, Lies igonres Coward because it's not the card itself that causes an honor loss but the ability printed on it. I also think you (or some other Rules guy) have already answered a similar question using this explanation.
