Based on the provided legal document, here are the key points:

• It is a settled proposition of law that punishment not prescribed under the rules cannot be awarded as a result of disciplinary proceedings. (!) (!) (!)
• The imposition of punishment for a proved delinquency is regulated and controlled by statutory rules, and quasi-judicial authorities are not permitted to ignore these rules. (!) (!)
• Withholding an integrity certificate merely does not cause stigma but makes a person liable to face very serious consequences. (!) (!)
• The order passed by the Disciplinary Authority withholding the integrity certificate as a punishment for delinquency was without jurisdiction because it was not provided under the U.P. Police Officers of the Subordinate Ranks (Punishment and Appeal) Rules, 1991. (!) (!)
• Since the punishment (withholding integrity certificate) was not listed in Rule 4 of the 1991 Rules (which lists Major and Minor Penalties), the order is outside the purview of statutory rules and is a nullity that cannot be enforced. (!) (!) (!)
• The rules do not empower the Disciplinary Authority to impose "any other" major or minor punishment beyond those explicitly prescribed. (!)
• The analogy of nulla poena sine lege applies, meaning a person should not suffer a penalty except for a clear breach of existing law; similarly, in service law, punishment not prescribed by statute cannot be imposed. (!)
• The revisional authority and appellate authorities committed a mistake by not rectifying the error of imposing a non-prescribed punishment, showing a total non-application of mind. (!) (!)
• The grievance raised by the appellant regarding the recording of past criminal history in bailable offences was not considered by the authorities, constituting a failure to apply their mind to the grounds of appeal. (!) (!)
• The appeal was allowed, and the impugned orders withholding the integrity certificate for the year 2010 and all subsequent orders were quashed. (!) (!)
• The respondents are directed to consider the appellant's case for all consequential benefits, including promotion, afresh in accordance with the law. (!)
