Chris Gallavin: Massey University Law Professor on the Court of Appeal finding the Waitangi Tribunal can summon Karen Chhour

It's thought a Court of Appeal decision finding the Waitangi Tribunal could summon ACT MP Karen Chhour doesn't set a precedent for future cases.  The decision overturned a High Court ruling which found the Children's Minister did not have to front with her reasoning for removing Section 7AA from the Oranga Tamariki Act.   Massey University Law Professor Chris Gallavin told Mike Hosking that lots of ministers have given evidence before the tribunal in the past.  He says it's a bit of a storm in a teacup.  Gallavin says there's lot of agreement between the High Court and Court of Appeal, and they just took different views on one point.  LISTEN ABOVE  See omnystudio.com/listener for privacy information.
