4.2.4-1 May a broadcasting organisation that wishes to include a third-party work (not produced by itself) in its programme simply broadcast this work without further ado?

No, only the author (or the natural person to whom the copyrights have been assigned) has the right pursuant to Art. 10 para. 2 (d) CopA to broadcast the work by radio, television or similar means, including by wire. The broadcasting organisation therefore needs to obtain the author’s consent.
