Certainly. Based on the provided legal document, the key points are as follows:

1. The grant of selection grade to employees is to be reckoned from the date of regularization in service, not from the date of ad hoc or temporary appointment (!) (!) .

2. The power of the High Court under Article 226 includes the authority to exercise review to prevent miscarriage of justice and correct grave errors, but this power is distinct from an appellate review and cannot be used to re-argue the case on merits (!) (!) .

3. An error apparent on the face of the record is one that is self-evident, patent, and does not require lengthy reasoning to establish; such errors can be corrected through review proceedings (!) (!) .

4. Orders passed on the basis of incorrect or irrelevant authorities, or based on erroneous concessions, are subject to correction if such errors are self-evident (!) (!) .

5. Concessions made by parties, especially those that are incorrect or based on misapprehensions, should be carefully scrutinized, and courts have the authority to recall or rectify such orders if they are found to be based on mistake or misstatement (!) .

6. The primary criterion for determining entitlement to benefits such as the grant of selection grade is the date of regular appointment in accordance with recruitment rules, rather than earlier ad hoc or temporary appointments (!) .

7. The legal position is that the period of service for the purpose of granting benefits like selection grades must be counted from the date of regularization, and prior periods of ad hoc or temporary service do not qualify unless explicitly specified (!) (!) .

8. The role of advocates and legal representatives is fundamental; they are expected to act with sincerity, honesty, and professionalism, assisting the court in a properly prepared manner, and upholding the integrity of the legal process (!) (!) .

9. Courts have an obligation to ensure that their orders are based on correct facts and law, and they possess the inherent power to review and correct mistakes, especially when such mistakes are self-evident and could lead to a miscarriage of justice (!) (!) .

10. Orders based on concessions or statements that are incorrect or based on misapprehensions can and should be revisited and corrected to uphold the principles of justice and fairness (!) (!) .
