When there is a blood case, the HLC members are first notified.
If there is a legal battle, the HLC calls Legal. A legal team of JW lawyers is flown to the ailing JW, and is appointed to defend the JW. In the sextuplets, this is what happened. In Dennis Olberg, Jr. (Seattle boy), this is what happened. In Bethany Hughes, this is what happened. If Bethel does not have a lawyer who is admitted to practice law in the jurisdiction, then Bethel usually pays an attorney who is admitted. But, Bethel "advises" the paid attorney on every element of its argument.
I don't know if the lawyer for Ms. K was a JW or not. If he wasn't, he was working on JW money.
