Some sanctions, similar to countermeasures under international law, introduce measures that would have been illegal if they were not adopted in response to a violation. Rights that sanctioned states and their citizens were entitled to pre-sanctions are no longer guaranteed under a sanctions regime.
Sanctions may contradict contractual obligations of the sanctioning state – for instance, if trade agreements are unilaterally terminated as a result of the newly introduced trade restrictions.
Assuming that the right to free movement applies extraterritorially, the imposition of travel bans effectively deprives sanctioned persons from the enjoyment of this right.
Some sanctions introduce measures that may be unfavorable to the sanctioned states and their citizens but remain within the lawful discretion of the sanctioning state.
Assuming that diplomatic measures fall under the broad umbrella of sanctions, calling back diplomatic missions or limiting the number of diplomats stationed in a particular state is within a sovereign state’s discretion.
Choosing to limit the access of certain state officials to official events or sports competitions is also within the discretion of the sanctioning state or organization. The sanctioned state cannot expect an invitation as a matter of right; it is only granted as a matter of privilege.
