The Multidisciplinary Boardroom

Every serious corporate decision today is written in three languages at once. The legal asks whether a thing is permitted and who answers if it is not. The fiscal asks how value is characterised, where it sits, and at what rate it is taxed. The technological asks whether a system works, scales, and ships before a competitor's does. No single person in the room speaks all three, and the decision lives in the space between them, where the regulator's letter, the tax reassessment, and the press inquiry are born.

The Multidisciplinary Boardroom is a field guide for the executive who must say yes or no at that crossing. Drawing on the author's six years judging these collisions from the bench of a European data-protection authority, it shows where law, tax, and artificial intelligence actually collide, why even able boards misjudge the collisions, and how one person can learn to translate between the three without mastering any.

Part I diagnoses why the room falls silent, from the boundaries that knowledge fails to cross to the quiet turf war between professions. Part II explains how the mind misjudges, from bounded rationality and the planning fallacy to the invisible noise in a deliberating group. Part III takes four real, costly collisions one at a time: training data against the GDPR, consent architecture against responsibility, a tax structure against the global minimum tax, and a product against an AI Act whose deadline keeps moving. Each is anchored in a primary legal instrument and a quantified case. Part IV delivers the method: the cast of mind of the translator, the boundary objects a board can build, and a single set of questions, with a twenty-minute pre-mortem, that would have caught every failure in the book before it happened.

Rigorous, current to mid-2026, and written in deliberately plain language, this is the most practical guide available to the place where law, tax, and technology stop speaking the same language, and to the executive who must make them speak again.
