Dowry Death Cases u/s 304-B & 498A: Guidelines
The import of Section 304-B is quite different from 498A. They cannot be held to be mutually inclusive. They deal with two distinct offences. Cruelty is a common factor in both the sections.
Under Section 304-B dowry death alone is punishable. Such a death should have occurred within seven years of marriage. In Section 498-A no such period is mentioned. If the case is established, there can be a conviction under both the sections.
