  • Reciprocity
  • Non-subordination
  • Cultural integrity
  • Free, prior, and informed consent
  • Indigenous data sovereignty

Submission of correspondence does not establish an alliance, governmental relationship, legal representation, endorsement, or contractual obligation.

Formal relationships arise only through an instrument, appointment, authorization, or decision issued by the appropriate authority of the Nation.

Use of the Nation’s name, seal, insignia, leadership titles, photographs, statements, or institutional identity requires prior authorization where applicable.

Official Records and Privacy

Correspondence received by the Nation may become part of its governmental or institutional records.

The Nation protects confidential, personal, cultural, diplomatic, and legally sensitive information according to its own policies, agreements, and Indigenous data-governance principles.

Public submission does not authorize:

  • Creation of derivative materials
  • Misrepresentation of the Nation’s position
  • Use of the Nation’s name or symbols
  • Disclosure of protected family or cultural information

Persons submitting confidential information should clearly mark the communication:

CONFIDENTIAL — OFFICIAL CORRESPONDENCE

Marking a communication confidential does not by itself create a legal privilege or confidentiality agreement, but it assists the Nation in routing and handling the material appropriately.

A response may be issued by:

  • The Grand Chief
  • The First Lady
  • An authorized governmental officer

Only communications issued through an authorized Nation email address, signed governmental document, verified public statement, or formally appointed representative should be treated as an official position of the Hunnic Matinecock Tribal Nation.

Persons seeking to verify a communication, appointment, agreement, or representative may contact the Office of the Grand Chief.
