Sam2 -“You still need a Dayan, though, and to be Kasher for Dayanus you need Smichah. You still need a Kosher Eid (meaning a Jew, not a Goy). It’s a Misas Beis Din. There is just a more lenient requirement here for what constitutes a Beis Din and what constitutes testimony.”
You’re wrong! The Dayan & the Eid can be Goyim. The Rambam comes from Sanhedrin 56b.
Look it up!
