HCN has updated their own tribal rules of civil procedure to allow for a pro hac waiver in tribal court for child welfare cases:
(C) Counsel not admitted to practice before the Ho-Chunk Nation Courts, but seeking to appear on behalf of a federally recognized Indian tribe in a proceeding regarding a petition for guardianship or for child protection over a child who is a member of that tribe, or eligible for membership in that tribe, shall be permitted to appear without paying any fee. Counsel representing an Indian tribe in such a matter shall also be permitted to make their appearance without filing a motion for special appearance, provided that, at that appearance, said counsel states on the record that they are admitted to practice in another state, federal, or tribal jurisdiction; that they have been in actual practice for two or more years, and takes the oath or affirmation for practice. This rule shall not apply to attorneys who appear on behalf of the Ho-Chunk Nation.
HCN Civ. Pro. R. 16(c)
We’ve updated the pro hac page accordingly. Obviously these are not ICWA pro hac waivers, but are related and can be used to show comity in this area.
