Where to place the authority to determine interference

The options

The order shown is not a ranking of preference.

1. Option 1

   Exclusive authority of a joint tribunal

   Provides consistent judgment for interference disputes among participating zones, but transfers local coordination authority and bears the standing operating costs.

2. Option 2

   Zone-level adjudication with mutual approval

   Preserves local accountability and existing hearing capacity, but the time needed to reconcile conflicting decisions may lengthen.

3. Option 3

   Case-by-case joint mediation

   Forms a hearing body suited to the use and impact zone of each case, but the composition and procedure must be negotiated for every case, which can delay the response.

The situation as it stands

If the placement of adjudication authority is not settled at renewal, the existing zone-level procedures will continue, and conflicting demands and hearing delays over the same interference events will persist.

The fictional Adjacent Substrata Convention Assembly and the fictional autonomous districts participating in it

1. Premise 1Synthetic premise: the participating autonomous districts are collecting observation data on aquifer, geothermal, and storage uses in a common format. A demand from one zone to adjust its use conflicts with existing commitments in another zone, revealing that sharing data alone does not determine who adjudicates.
2. Premise 2Synthetic premise: the convention assembly can change the contractual dispute procedures delegated to it by the participating zones, but cannot exercise authority over non-participating zones. Funding the standing operating costs of a joint adjudication body would reduce, from the same budget, the programs that fill observation gaps.
3. Premise 3Synthetic premise: the established operators do not want to be asked to coordinate in conflicting ways across zones. Small autonomous districts worry their voice will weaken in the joint body, and a community that reported impacts late objects to the originally approving zone retaining adjudication authority.

Where it holdsAdopt a convention that places the authority to adjudicate interference between different underground uses, within the scope agreed by the participating zones.

What can be lost

• Established operators: conflicting coordination demands could raise contract performance costs and operating uncertainty.
• Small autonomous districts: delegating adjudication authority could cost them direct control over decisions that affect residents.
• Communities that reported impacts: if jurisdictional disputes drag on, they could lose the practical opportunity to have harm confirmed and to seek adjustments to use.

What is still unknown

1. Unknown 1It is unknown to what extent the effects of each use and cumulative interference can be distinguished using observation data in a common format alone.
2. Unknown 2It has not been confirmed whether the joint body's accumulation of expertise will reduce the information advantage of large operators, or instead make others dependent on their data.
3. Unknown 3Whether existing decisions will be accepted if a currently non-participating zone is included in an impact zone or joins the convention has not been settled.

Signals to decide again

• The convention secretariat cross-checks case records each quarter to see whether conflicting coordination demands are being issued over the same events.
• An independent procedural auditor investigates every half year whether the gap in hearing waiting periods and participation costs per party is widening.
• The joint observation lab reports to the annual boundary review on whether the impact zones recognized through observation and the convention's participating zones are out of alignment.
