211.—Where in any proceedings for infringement of any right conferred by Part III or IV the question arises as to whether a recording is an illicit recording and it is shown that— 
   | 
| 
 |  | 
(a) the recording is a recording of the performance concerned, and 
   | 
| 
 |  | 
(b) rights conferred by Parts III and IV subsist or have subsisted at any time in the recording, 
   | 
| 
 |  | 
it shall be presumed until the contrary is proved that the recording was made at a time when such rights subsisted.
