دون تابع

Arabic to English Law/Patents Law (general) Bahraini document

This pertains to an insurance company trying to claim money from the insured who has lent his car to someone who had an accident.

The sentence goes like this:

وكان الحكم المطعون فيه قد استخلص أنه قادها دون تابع المطعون ضدها (المؤمن لها)

Is تابع supervision/oversight etc. in this context? Thanks...
