Section 498A IPC: Har Pal ka Kya?

Har Pal is an Indian citizen and a resident of Punjab. His wife, Rukmini, left her parental home three months ago, citing 'cruelty' by her husband's family members. Rukmini's mother files a complaint against Har Pal and his family under Section 498A IPC, alleging that they harassed her for dowry and emotionally abused Rukmini. But here's the twist - the police investigation reveals that Rukmini had been planning to separate from Har Pal for a long time, and she had multiple conversations with her friends about it. Moreover, Har Pal was not involved in any dowry demands or physical abuse. What legal remedy can Rukmini's mother apply to get justice?
