Minni’s counsel Advocate Makkia Fatema Islam filed the petition with the HC bench concerned on Tuesday.
On Sep 30, Minni and five others were sentenced to death by District and Sessions Judge Md Asaduzzaman over his killing in Barguna in broad daylight last year.
The full verdict of the case was published on Oct 3 and the death reference reached the High Court Division the next day.
Rifat, 22, was hacked to death in the district town on June 26 last year.
He was attacked near the main gate of Barguna Government College. Surveillance camera footage showed his wife Minni apparently trying to save him from the attackers.
Rifat’s father filed a murder case accusing 24 people. Although Minni was initially named as a witness, she was later arrested on July 16 last year and made an accused.
Sabbir Ahmed alias Nayon Bond, the main accused, was killed in an alleged gunfight with police on July 2 that year.
Minni and nine others were indicted for Rifat’s murder on January 1.
Meanwhile, 14 other underage accused are being tried separately at a juvenile court for the killing.
