Maddahinasab Legal Advisory Presents

Interregnum Counsel

About the Publication

Legal analysis built for the pace of transitional markets

Each issue follows the same disciplined sequence: establishing the relevant developments and the background needed to understand them, assessing the legal mechanics at play, drawing out the commercial and investment implications, and closing with a forward-looking scenario and MTRIS™ decision framework.

The first three monthly issues are devoted to a single case — the renewed escalation between the United States and Iran — each applying the same underlying analysis through a different sector: energy, then supply chains and transportation, then banking and financial services. A quarterly report consolidates all three into one holistic assessment.

Hormuz and Beyond: Supply-Chain Reconfiguration Under Dual Chokepoint Pressure

Covers Oman–Iran maritime governance discussions, contractual force majeure and change-in-law exposure for logistics operators, and closes with a Predictive Watch List and MTRIS™ Intelligence Index assessment across all three analytical layers.

Frequently Asked

About Interregnum Counsel

How often is Interregnum Counsel published?

Interregnum Counsel is published periodically as material developments occur in transitional markets, rather than on a fixed calendar. The first three issues follow a monthly cadence, each applying the same underlying legal analysis of U.S.–Iran tensions through a different sector — energy, then supply chains and transportation, then banking and financial services.

Is Interregnum Counsel free to subscribe to?

Yes. Interregnum Counsel is delivered by email through Substack, free of charge. New issues arrive by subscription as soon as they are published, ahead of their archival on this page.

What is the difference between Interregnum Counsel and the Research page?

Interregnum Counsel is a periodic legal intelligence letter tracking specific, timely developments — such as a sanctions policy shift — as they happen. The Research & White Papers page hosts standalone, in-depth MTRIS™ market outlooks that are updated less frequently and cover a market's legal architecture more broadly.

Who writes Interregnum Counsel?

Interregnum Counsel is written by Mostapha Maddahinasab, Ph.D., Founder and Principal Advisor of Maddahinasab Legal Advisory and architect of the MTRIS™ framework applied throughout the publication.

Can I cite Interregnum Counsel in my own research or reporting?

Yes. Each issue carries a permanent reference code and a suggested citation format, and forecasts published in the Predictive Watch List retain a permanent reference code that is revisited and reassessed in later issues.
