Engel vs Yeshivah Centre

Mordy Engel has been having a machlokes with Yeshivah Centre for a long time
They wanted to sack him but he got an ikul from Sydney Beis Din
Then Telsner ruled it was OK to sack him so they did
Telsner is also employed by the Yeshivah
Engel has been taking Yeshivah to Beis Din over this
Gutnick from Sydney is borer for Engel and Kaminetzky is borer for Yeshivah
They have been arguing for months over getting a sholish
Somehow Sydney Beis Din is also involved
Now Kaminetzky writes a nasty letter to Sydney Beis Din
Sydney Beis Din respond by putting him in cherem and also with a letter to the Yeshivah executive

How can Telsner rule against Sydney Beis Din?
Also, he works for the Yeshivah so he has a conflict
Why is Sydney Beis Din involved if this is a zablo?
Can Gutnick be Engel’s borer and also on Sydney Beis Din in the same case?
The only thing everyone agrees is that Kaminetzky is an animal
