Paragraph

Where a person has been insured under the legislation of more than one Party, the competent authority in the territory of the Party whose legislation was applicable when incapacity for work followed by invalidity began shall determine, in accordance with its legislation, whether the person concerned satisfies the conditions for entitlement to invalidity benefit taking account, where appropriate, of any insurance period which that person has completed under the legislation of any other Party as if it were an insurance period completed under its legislation.
