Illegal land encroachment and selling issue

Sir/Madam, I respectfully request legal advice concerning a matter of land settlement, the details of which are as follows: In 2018, the Government of Bihar issued an order for the allotment of free land to members of the Scheduled Caste community. The beneficiaries received official written documentation from the government confirming this allotment. However, certain land mafias, comprised primarily of refugees of Bangladeshi origin, in collusion with local politicians and public officials, including the District Magistrate and other officers, are engaged in the illegal sale and settlement of the aforementioned land. These individuals possess no legal title or valid documentation pertaining to the land in question. To obstruct the lawful settlement and perpetuate their illegal activities, these land mafias have devised a strategy of repeatedly filing frivolous writ petitions in the High Court, in violation of the principle of res judicata, thereby creating a false impression of ongoing sub judice proceedings. Exploiting this tactic, public officials, including the District Magistrate, are misleading the Scheduled Caste beneficiaries by falsely asserting that the land settlement cannot proceed due to pending sub judice matters. The proceeds from the illegal sale of this land are being used by the aforementioned refugees to sustain their daily living and fund their legal representation in the High Court. Numerous writ petitions filed by these refugees on baseless grounds have been consistently quashed by the High Court, which has repeatedly acknowledged their lack of legal standing. In a recent case concluded in 2024, originating in 2021, the High Court strongly reprimanded the refugees for their vexatious litigation. Notwithstanding these prior judicial pronouncements, the refugees have filed another writ petition in 2017, which remains pending, again based on unsubstantiated claims. This pending petition is now being used to create a false narrative among their illegal purchasers and public officials, suggesting an imminent favorable outcome. The primary objective of these actions is to prolong the dispute indefinitely, while generating funds through illegal land sales and bribing public officials. The matter has been adjudicated in Lok Adalat on multiple occasions, where judicial officers have reprimanded the involved officials for their malfeasance and issued ultimatums for the settlement of the Scheduled Caste beneficiaries within three months. This occurred in 2021, but the officials effectively disregarded the Lok Adalat's orders by facilitating the filing of further frivolous litigation. Since 2018, numerous hearings have been conducted by various authorities, who have consistently misled the Scheduled Caste beneficiaries with verbal assurances of land possession, while simultaneously citing the fabricated sub judice status as a pretext for inaction. It has been concluded that the dummy cases have no relation to the aforementioned land. Despite these obstacles, the Scheduled Caste beneficiaries have obtained the parcha of the land. However, on the day scheduled for the official demarcation of the land, an order was issued, citing the alleged sub judice status, to prevent the settlement. I seek your expert legal advice on the appropriate course of action to secure the rightful land allotment for the Scheduled Caste community and to hold the involved individuals accountable for their illegal activities.
