If you've been falsely accused under Section 307 IPC and granted anticipatory bail, but the case has stalled for a year with no charge sheet filed, you can request the court to direct the police to file the charge sheet expeditiously. Due to current pandemic-related delays, you may need to wait for courts to resume normal operations before filing such a petition. Until summoned, you generally don't need to worry excessively, especially if the police investigation suggests the charges are false.
