4.2.2-2 Does the principle of exhaustion pursuant to Art. 12 para. 1 CopA apply if a copy of a work produced without any authorisation (‘piracy’) is sold?

No, a work may only be freely resold or used in any other way if authors sell the work themselves or allow another person to sell the work. This does not apply here (cf. Barrelet/Egloff, Urheberrecht, 3rd edition, 2008, Art. 12 N. 9).
