Brown v. Fletcher (235 U.S. 589…
“ The rights of the beneficiary here depended not upon an agreement between him and Braker, but upon the terms of the will creating the trust and the duty which the law imposed upon the trustee because of his fiduciary position. And a proceeding by the beneficiary or his assignee for the enforcement of rights in and to the property, held-not in opposition to but-for the benefit of the beneficiary, could not be treated as a suit on a contract, or as a suit for the recovery of the contents of a chose in action, or as a suit on a chose in action. ”
