It appears that you have a firm belief that appraisal is only for the salary hike and nothing else. Performance Appraisal (PA)
Performance Appraisal (PA) should be done as per the Policy on Performance Appraisal (PA). In your company, the appraisal cycle is from 1st July to 30th June. But then what is the due date by which the Manager must complete the PA report and submit it to HR? Going further, what is the due date by which the annual salary increment takes place? If the appraisal cycle ended on 30th June, then why has the salary increment not taken place so far?
Has the salary increment taken place for other employees? Is it that you have been left out from the increase because you are on a notice period? Is there any clause in the Policy on PA about a hike for employees who are on the notice period?
Please clarify the above points. Suitable suggestions can be given thereafter. As Prashant has said, there is no legal remedy for your problem.
Thanks,
