so far, Miss Khan did not claim that Pritam asked her to continue to lie.

there are no words from Pritam that asked her to continue to lie.
it means that there is no concrete evidence to charge Pritam for lying.

if there is no direct evidence, there is no way that PAP can charge Pritam for any offence.

PAP is trying to find evidence to suggest that Pritam encouraged Miss Khan to lie.
This kind of evidence is very weak because pritam can deny that he never suggest such thing.

Thus, Miss Khan is guilty and WP is innocent.

It should be noted that many a times, PS had been firm to say "I don't agree" to what EP had suggested or forced into PS mouth.  From the encounter, if can clearly be seen that EP is the one who faulted when he blatantly interrupted PS when PS is replying....but EP asked that they don't over speak over each other......
