Determination "cannot" question

L5R CCG Rules board, 13 April 2009

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.

http://rules.l5r.com/Glossary_C#Cannot (emphases mine): "In card text, when referring to entering play, targeting, attaching, using a trait, or taking an action, "cannot" is a restriction on the legality of that thing in the first place, not negation of its effects."

Above is a quote I recieved in a previous question regarding determination's ability to preform actions you would not otherwise be able to preform.

I have a follow up question: Assume Blanketed Forest is in play and my opponant and I both have 2 units at the battle. Is it legal for him to announce an action that would move one of his personalitys home and then play determination so it's effects cannot be negated? Or is it just ilegal to announce any movement to or from this battle at all?

I have pondered this and it seems to me that he would be able to do this because the "cannot" on blanketed forest is (I think) negation and not referring to entering play, targeting, attaching, using a trait, or taking an action? It's the taking an action that is on point. The personality in this case is not prevented from preforming actions so it seems to me that the cannot on blanketed forest is negation.

There is no "cannot" on Blanketed Forest.
