The court dismissed the review of a subsequent formal modification to a prior declaration. The plaintiff argued that the new form was valid, while the defendant contended that the original form was essential to the substance of the declaration. The court ruled that when form is required 'ad substantiam,' any later alterations must strictly adhere to the original formal requirements to ensure validity.
