We faced a criminal case. Case is as follows. 
In the execution of painting work on electrical  lines excess payment was released to the contractors. When noticed it was recovered from the contractors.  Measurement was done by junior engineers, I was SDO I varified the bills and Executive engineer passed the bills and made the payment to contractors. My part was that I did not exercise test checks on bills. But prosecution  has deposed that there was no suchpractice . Case was made that excess payment was released to give benefit to contractors by making connivance. We have agreed that due to some calculation mistake of measurement of tower excess payment was released.  Which was recovered duo motu from contractors without pointing out by any agency. FOR was registered after 5 years after the recovery on anonymous complaint.
I am a govt. Officer. My promotion was placed under 
sealed cover due to pendency of a criminal case. I submitted a writ in HC for early hearing of case. CJ directed the trial court to conclude the case within 3 months. The Ld Judge got ennoyed .In the trial court during cross examination of procecution witnesses the Ld. Judge did not allow to submit evidences in defence. He told to submit during defence case. Judge was not allowing proper cross examination of procecution witnesses. On the very next day we moved to the high court for change of trial judge. Ld CJ have stay on trial proceedings but later on some other Judge in HC dismissed the writ and directed us to give evidences during defence case. The case is based on the documentary evidences. Evidences were submitted during defence. One day before judgement the judge ammended the charge and took in writing from accused and pp that no cross examination is required.Not much cognigence of defence evidences was given by judge in judgement. He announced sentence to all accused . 
1. Can't an accused submit evidences  during cross examination of the star prosecution witness???  Pl advise whether we get some benefit in appeal  in HC? Support advice with citation.
2. Any citations on recovery of excess payment released to contractors. 
3.what shall be our stand in appeal in HC.
