Ameliа, Briаn, аnd Carоl are cо-trustees оf a family trust worth $40 million. The trust was created when their uncle Stevie Strauss passed away. The trust investments generate income that is paid out to Strauss's ten adult children. When the last of Stevie's children passes away, the trust principal will be distributed outright to all of Strauss's grandchildren then living. The trustees disagree about how to invest the trust assets. Amelia and Brian wanted to invest domestically in the United States in a range of different investment opportunities, while Carol wanted to invest internationally in a range of different investment opportunities. Amelia and Brian went ahead with investing domestically. Carol noted her dissent in writing, but did not resign from the trusteeship. If a beneficiary challenges this decision, what is the likely result?
