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

1. Filing a review application after approaching a superior court or tribunal is considered an abuse of the court's process and is generally not maintainable (!) (!) .

2. An order obtained through fraud on a competent authority is void and non-est in the eyes of law; such orders cannot be sustained (!) (!) .

3. Even in cases of illegal occupation, eviction must follow lawful procedures; forcible eviction without due process is unlawful (!) (!) .

4. The doctrine of merger of orders applies when a higher court or tribunal affirms or modifies a decision, but not when a review order is dismissed without a substantive decision on the merits (!) (!) .

5. The order refusing special leave to appeal does not merge with the order under challenge and does not bar subsequent review or proceedings (!) (!) .

6. The concept of fraud includes deceit, misrepresentation, suppression of material facts, and collusion, which vitiate proceedings and can lead to the annulment of orders obtained through such means (!) (!) .

7. Orders obtained by playing fraud or misrepresentation, or through suppression of material facts, are voidable and can be challenged at any stage, especially if such fraud is proved (!) (!) .

8. The burden of proof in cases under the relevant land laws, such as the Land Grabbing Prohibition Act, is on the accused to establish their innocence, and the law presumes guilt unless proven otherwise (!) .

9. Illegal land occupation cannot be justified without following proper legal procedures, and even trespassers are entitled to protection against forcible eviction unless lawfully dispossessed (!) (!) .

10. The courts emphasize that litigation should not be used as a tool for harassment or protraction of disputes, and repeated attempts to re-litigate settled issues are viewed as abuse of process (!) (!) .

11. The finality of judgments is recognized, but only when they are free from fraud, misrepresentation, or procedural irregularities; otherwise, such judgments can be set aside (!) (!) .

12. The appeals in this case were allowed because the High Court's order was found to be unsustainable due to failure to consider the above principles, including the abuse of process and fraud allegations (!) .

13. The judgments and orders of the lower courts, which correctly identified the land ownership and dismissed the respondents’ claims of fraud and misidentification, were restored (!) (!) .

14. Overall, the legal process must be respected, and any attempt to manipulate or mislead the court through fraud or delay tactics undermines the integrity of judicial proceedings.
