Anyone Know How TEC Rebels Can Ignore the Effect of Phase Jump Inhibitors

Hey guys just looking here for answers. So today in an online 5vs5 game a tec rebel player was able to be immune to the effects of phase jump inhibitors. The players fleet had titan level 6 akkan and frigates. First time it was noticed the player was jumping out beside one of his allies. The ally was affected by it while he was not. The phase jump inhibitors were not in range of the akkans armistice ability. He then moved back into a gravity well with phase jump inhibitors later on in the game and was still immune. Also to note is that the debuff that appears on all ships in range of phase jump inhibitors was not present on his ships ever. He had pacts with another tec player and had some artifacts but as far as I know none of these provide the ability to ignore phase jump inhibitors. Hopefully someone can clear up how this is possible.
