HRS §554D-302
When a power holder can act for others
This section says that a person who holds a power of appointment can act for and legally bind other people affected by that power, as long as there is no major conflict of interest between them on the specific issue. It only covers representation when interests align.

The statute, as written — Representation by holder of power of appointment
To the extent there is no material conflict of interest between the holder of a power of appointment and the persons represented with respect to the particular question or dispute, the holder may represent and bind persons whose interests, as permissible appointees, takers in default, or otherwise, are subject to the power.
