The allegations attract S.354-A of IPC anf S.10 of SC/ST Act. I understand the agony of being from general category. People belonging to SC/ST category misuses these provision blatantly and courts know that these are generally fake.
This is incorrect interpretation of the law that the girl was harassed because she is SC/ST. She was harassed and that is it. The harrasser never knew the complainant and that in itself is sufficient to defeat the application of S.10 of SC/ST act. Courts generally opt this fallacious interpretation and frame charges incorrectly.
Anyways. It is now clear how she has deposed and what is the judge's behaviour in the case. If you know that the girl is telling the truth and it is going to go against you, then compromise is the best policy. As rightly opined by my learned friend, you must get her cross-examination in your favor and then settle the case.
If you know she is lying then hire a competent lawyer who can ask questions as per the laid down law so that during arguments stage he/she can show that no case is made out against you as per deposition of the complainant.
All the best!
