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.

Say Mr.Crab Bushi receives a Force bonus of 2 in battle from an action card. His opponent then uses Justly Earned Victory to negate the bonus. The Crab player then uses his own Justly Earned VIctory to negate the force reduction caused by the first JEV's negation.
Is this legal?
When a bonus, penalty, maximum, or minimum ends or is negated, the resulting stat change is not considered a penalty or bonus.
Not legal.
