Right to Regulate in the Context of Expropriation

I. Definition


The right to regulate entitles the State to act in the public interest.1 Depending on the manner in which such right is exercised, arbitral tribunals have held that regulatory measures that lead to the taking of property may or may not constitute a compensable expropriation.2 In the context of a regulatory taking, a State’s right to regulate has been often used interchangeably with the doctrine of “police powers”. See also Public interestState Regulatory Power, Police powers doctrine.


Many tribunals have recognized that States have a right to regulate under customary international law regardless of whether such right is provided in the applicable investment treaty.3 A number of recent investment treaties further specify that legitimate measures adopted in the public interest do not constitute expropriation,4 except in rare circumstances.5

III. Distinguishing a valid exercise of the right to regulate from compensable expropriation

A. Assessment is fact-sensitive


Illegitimate exercises of the right to regulate can amount to regulatory expropriation.6 There has yet to be a comprehensive test to distinguish a valid exercise of the right to regulate from regulatory expropriation.7 Thus, the assessment of whether a regulatory measure is a legitimate exercise of the right to regulate is context-specific and depends on the facts of each case.8 Some factors identified by tribunals as indicative of a compensable expropriation having taken place include an assessment of whether the measure was:

  1. bona fide for the purpose of protecting public welfare (see further below),9
  2. non-discriminatory,10
  3. proportionate11 and
  4. enacted according to due process.12 

See further Police powers doctrine.

B. Whether the State's purpose should be considered


There is yet to be a consensus on whether the State’s purpose behind the measure should be considered in assessing whether it constitutes expropriation. Some tribunals held that the purpose of the measure should be taken into account.13 Other tribunals have applied the “sole effects” doctrine and held that one should look at the effects of the measure solely and not the purpose behind it.14 See Sole Effect Doctrine. A third approach allows the purpose to be considered, but accords it only secondary importance.15

C. Instances where tribunals held that the right to regulate was validly exercised


Tribunals have identified the following types of measures as valid exercises of the State’s right to regulate:

  1. cancelling a license or concession because the investor failed to comply with the legal requirements to maintain it;16
  2. revoking a bank’s license where the bank was in serious financial distress;17
  3. forced administration of a bank in serious financial distress;18
  4. banning the sale and use of a gasoline additive to protect public health and the environment;19
  5. terminating the use of lindane (a type of pesticide) based products to protect public health and the environment;20
  6. restricting the marketing and packaging of cigarettes to protect public health;21
  7. financial and monetary measures to cope with a severe economic crisis;22
  8. introducing taxation measures;23 and
  9. depriving an investor of its mining rights for the protection of the environment.24
