Though a conflict may at first sight seem to exist between section 13(4) and section 14(1) (a) (iii) on the one hand and sec tion 14(1) (c) (ii) on the other, a close scrutiny and a harmonious and rational instead of a mechanical construction of the said provisions cannot but lead to the irresistible conclusion that once the author of a lyric or a musical work parts with a portion of his copyright by authorising a film producer to make a cinematograph film in respect of his work and thereby to have, his work incorporated or recorded on the sound track of a cinematograph film, the latter acquires by virtue of section 14(1) '(e) of the Act on completion of the cinematograph film a copyright which gives 221 him the exclusive right inter alia of performing the work in public i.e. to cause the film in so far as it consists of visual images to be seen in public and in so far as it consists of the acoustic portion including a lyric or a musical work to be heard in public without securing any further permission of the author (composer) of the lyric or a musical work for the performance of the work in pub lic.
