The Maori Women's Welfare League split with Destiny Church looks set to be the subject of a court case later this month.
Auckland-based Destiny co-leader Hannah Tamaki says she is standing in the election to become the new president of the league but has been dropped from ballot papers.
Her lawyers filed proceedings in the High Court at Wellington today.
The case has been tentatively set down for July 20.
The church has established branches of the league since Tamaki joined five years ago.
But yesterday the league said it was suspending its link with those branches and church members pending an inquiry.
