Are Indian Tribe accounts considered Public Funds accounts? If so, can anyone point me to the legal reference, please?

I would start here.

Thank you Califgirl!

I doubt the local agency funds law applies since tribes are sovereign nations, not a public entity.

53630. As used in this article:
(a) "Local agency" means county, city, city and county, including
a chartered city or county, a community college district, or other
public agency or corporation in this state.

But . . . . take a look here: https://www.law.cornell.edu/uscode/text/25/162a
