Paragraph

Any claim, notice or appeal, which should, for the purpose of the legislation of one Contracting Party, have been submitted to an insurance authority or other authority of that Party, shall be treated as if it had been submitted to the appropriate authority if it has been submitted to an authority of the other Party concerned with social security. The day on which the claim, notice or appeal is submitted to that authority shall be considered as the day of submission to the appropriate authority.

In any such case, the authority to which the claim, notice or appeal has been submitted shall transmit it without delay to the appropriate authority of the other Party.
