So which wins? If I JEK a courtier and he Power of the Words it, can I just choose to negate it and then it not be negated?
Power of the Word vs Journey's End Keep
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.
If I JEK a courtier and he Power of the Words it, can I just choose to negate it and then it not be negated?
Yes, you can, and it would then just not be negated.
By the way, no need to imbed the giant images in the post; a link to the Oracle page will do just fine.
And also, please try to use the forum Search before asking, in case your question was already answered, as it was here.
