5.May that it be, this Court is of an opinion that appointment can never be claimed as a matter of right. This apart, the writ petitioner claims that he must be appointed as Mechanic on daily wage service. Such an appointment cannot be claimed by the writ petitioner by stating that he had participated in the interview. Mere participation in the interview will not confer any right to the candidate. If there is any irregularity, malpractice or corrupt activities, then the process of selection itself can be challenged. In such event, a person who was participating in the selection process has to establish the irregularity or malpractice. In the absence of any substantial proof in this regard, the claim of the candidate for appointment cannot be interfered at all. This apart, the writ petitioner claims that he must be appointed as Mechanic on daily wage basis. Now the claim as such after a lapse of so many years cannot be granted and the writ petitioner has to participate in the open competitive process for securing public employment in accordance with the rules in force.
