Neither Rules Nor Standards

Specifying the content of a requirement or a prohibition up front — e.g. replacing a “reasonable speed” requirement with a fifty-five miles per hour speed limit — can make life easier for enforcers and citizens alike. Recent efforts to substitute international tax rules for decades-old standards may do just the opposite, jeopardizing the “miracle” that is today's international tax regime. Enhanced information exchange and formulary apportionment will undermine the legitimacy that is essential to the success of any international legal regime.

Only then will it meet today's tests as successfully as it once rose to the challenge of double taxation
