At 1:19 into this BBC news, the BBC reporter says:
But what pushed her from office was ___ constitutional court finding her guilty of crime in a country which has only been a democracy for 30 years.
Did he say "a" or "the" in the blank?
It sounds like "a" to my ears. But I think it may well be "the", because at the beginning of the video, the same court has been mentioned.
Now, my question is whether "a" is ever possible or even natural in this context?
And in general, can choosing "a something" over "the something" be natural even when that "something" is previously mentioned?
EDIT
FYI, there is only one constitutional court in South Korea.
