Hon’ble Apex Court has in this judgment held that,

Legal Point #1:

The above provisions indicate that whereas Section 190(1) empowers the Magistrate to take cognizance of any offence, upon receiving complaint of facts which constitute such offence; upon police report of such facts; upon information received from any person other than a police officer or upon his knowledge that such offence has been committed, Section 198 which relates to prosecution of offences against marriage brings in the concept of complaint by an aggrieved person and Section 198(1)(c) explains how far the scope of term ‘aggrieved person’ can be extended in the context of offence under Section 494 of the IPC.

Legal Point #2:

A conjoint reading of the above provisions makes it clear that a complaint under Section 494 of the IPC must be made by the aggrieved person. Section 498A does not fall in Chapter XX of the IPC. It falls in Chapter XXA. Section 198A which we have quoted hereinabove, permits a court to take cognizance of offence punishable under Section 498A upon a police report of facts which constitute offence. It must be borne in mind that all these provisions relate to cognizance of the offence by the court.

Therefore,

Above provisions, lead us to conclude that if a complaint contains allegations about commission of offence under Section 498A of the IPC which is a cognizable offence, apart from allegations about the commission of offence under Section 494 of the IPC, the court can take cognizance thereof even on a police report.

In addition to CrPC 155(4), legislature brought in CrPC 198A specific to IPC 498A.
