Proportionality Test

When authorities restrict your rights—whether through taxation, regulation, or enforcement—they must justify that the limitation is necessary and not excessive. The proportionality test is the legal framework courts use to evaluate whether such restrictions are justified, weighing the government's legitimate goal against the burden imposed on individuals. For expats, understanding this principle matters because it determines whether you can successfully challenge rules that affect your residency status, work permits, business operations, or personal freedoms in your host country.
