Can the respondent No. 2 and 3 file an appeal against an adverse order passed by the Single Judge

Can the respondent No. 2 and 3 file an appeal against an adverse order passed by the Single Judge of High Court in a Crl. M.C filed by the petitioner aggrieved by the dismissal of its 156 (3) Complaint Case filed against Respondent No. 2 and 3 by the Ld. CMM Court, upon getting a detailed status report from the Investigating officer. where material facts were suppressed by the petitioner, the petitioner had intentionally not filed the complaint under section 200 Cr.P.C. and had confined to resorting to the relief only under section 156(3) Cr.P.C. as the intent of the petitioner was to file only complaint u/s 156(3) of Cr.P.C. and somehow get an FIR registered and make the answering respondent succumb to all unreasonable demands otherwise the petitioner being in knowledge of the entire facts could have proved the same in its evidence under section 200 Cr.P.C. but the motive of the petitioner since inception was malafide as it only wanted registration of an FIR against the answering respondent to defame, scandalize the matter and cause prejudice to answering respondent.
