Correction: It's Gaden Choeling Monastery in Phedong that was threatened, not Samten Choeling.
It's really sad to see such dispute happening between the two parties. The ban has really created something so ugly, making people be very greedy of possession and power that they would wrongfully claim what is not theirs.
If there was no ban, such incident would not happen as Domo Geshe Rinpoche's monasteries would be in harmony with each other. It is a huge disappointment that Tharpa Choeling would abandon their teacher and side with the Dalai Lama...
