Final answer:
Authorized representatives will sign the Commission Trust Agreement, which is a legally drawn, duly signed, and certified document. International agreements may specify an authoritative language version to prevent discrepancies.
Step-by-step explanation:
The "Commission Trust Agreement" will be signed by authorized representatives of the parties involved in the agreement. Documents like treaties, contracts, and commissions are often legally drawn, duly signed, and certified by parties who understand and accept the conditions laid out within them.
In cases involving international agreements, discrepancies in interpretation may arise due to language differences, which is why a version in a mutually agreed upon language may remain authoritative, as is hinted at with the mention of a 'French text' in the examples provided.
