Resource constraints, authority differences, and how cases develop. Germany, Ireland, Luxembourg compared.

EU establishment determines lead supervisory authority. The regulatory consequences of that decision are often underestimated.

Over 85% of filed cases remain undecided for months or years. What the complaint process looks like in practice.

The factors visible across enforcement outcomes, and what distinguishes cases that result in fines from those that do not.

EU platforms must report seller income data to tax authorities. What triggers reporting, what is excluded, and how the data flows.

Designed for copyright enforcement. In practice the mechanism operates differently, and the incentive structure explains why.
