If you remember back, far back, you'll remember a time when GLORY was proud to announce the acquisition of the K-1 tape library and K-1 was quick to retort that they hadn't and that anything that they did buy was not a legal sale. So the recent announcement that UFC Fight Pass had acquired over 100 K-1 events from GLORY was sure to raise their ire.
Earlier today K-1 Global issued a press statement explaining that this matter is still under legal scrutiny in Japan and that they are still refuting that GLORY actually bought anything back in 2013. What will come of this is anyone's guess, but K-1 seems adamant on this issue. K-1 has been moderately dormant of late, their latest outing was an amateur tournament in Italy run in conjunction with Carlo di Blasi.
K-1 Global currently sanctions K-1 Japan events, though. The last K-1 World Grand Prix that was ran by K-1 Global concluded in 2013 with Mirko Cro Cop emerging victorious. The last K-1 World MAX that they ran saw Enriko Kehl victorious.
Seeing as though the UFC went through with this deal I'm under the assumption that they were comfortable with whatever documentation that GLORY had. For now it looks like the only hope that K-1 has in this matter is for the legal system in Japan to decide in its favor.
