The law says that MKs who split off of a Knesset faction suffer sanctions UNLESS they fulfill one of three conditions:
B) The split is along party lines, in a Knesset faction made of multiple parties;
C) They split in protest of their faction's decision to merge with another faction.
Any one of these is sufficient.
* Gantz's "Israel Resilience"
* Lapid's "Yesh Atid"
* Ya'alon's "Telem"
This fulfills condition "A".
Sanctions include:
* No ministry appointments
* No running with existing parties next election.
Or they can just pass a new law allowing them to split.
