Key legal question
Whether the disputed amount exceeded the jurisdictional threshold because the declaratory relief on the cost-sharing rule had independent value.
Extracted holding
The rule-fixing claim had independent pecuniary value because it governed the parties' future relations beyond the claimed annual payment.
Extracted reasoning
A declaratory action is admissible when it has a proper independent purpose; here the judicial fixing of the cost-sharing key was not merely preparatory to the payment claim and therefore had to be counted in the value in dispute.
