In the Representation of V Trustees Limited the Royal Court of Jersey state that “… what we do accept is that Mr A will never be satisfied and will continue to ask questions. While some of those questions may be justified, a number of the assertions he made meant it was clear to us that Mr A would always be asking questions seeking information and challenging the Trustee’s decision. He will therefore always be putting the Trustee to significant cost and expense.”

Description

Attend and earn 7 CPD hours

11.15am to 12.15pm The Effect of Tikanga on Interpretation of Trust Deeds

 

The courts are increasingly utilising Tikanga Māori to assist in the interpretation of trust deeds, particularly in Te Kooti Whenua Māori. This reflects the increasing prevalence of Tikanga as law in judgments from the senior courts generally, and it also reflects a growth in litigation concerning PSGEs (post-settlement governance entities) which are usually set up as trusts.

  • Survey recent cases on the use of Tikanga in interpreting trust deeds
  • Examine when and how Tikanga may affect the interpretation of "plain English" drafting
  • Discuss the types of disputes in which these issues are likely to arise, both those involving intra-iwi or intra-hapū litigation and/or PSGEs, and the possibility of Tikanga influencing more traditional "private" family trust disputes

Presented by Scott Fletcher, Barrister, Thorndon Chambers

4.00pm to 4.15pm Afternoon Tea
1.15pm to 2.00pm Lunch Break
