In an Indian child custody proceeding, as defined in subdivision (d) of Section 224.1, the court shall give full faith and credit to the public acts, records, judicial proceedings, and judgments of any Indian tribe applicable to the proceeding to the same extent that such entities give full faith and credit to the public acts, records, judicial proceedings, and judgments of any other entity regardless of whether the Indian child’s tribe exercises the right to intervene under Section 224.4.
