The verdict was handed down by Luxembourg’s Court of Appeals on Tuesday, after the woman initially received an 18-year prison sentence with 13 years suspended.
The incident unfolded on 3 May 2021, as the 44-year-old man and his sister, 36 at the time, were residing with their mother.
A heated argument erupted within the family home, escalating quickly. Fuelled by alcohol and cannabis, the victim verbally and physically attacked his sister while both were in the kitchen.
In response, the sister forcefully pushed him away, causing him to stumble and fall to the floor. She then pounced on him, grabbed a kitchen knife from the worktop and stabbed the victim five times in the back, resulting in his death by the time the police arrived.
The Court of Appeals explained its decision to suspend the sentence by invoking the behaviour of the 44-year-old victim leading up to the crime.
Reports indicate he had subjected his family to constant verbal attacks, threats, and violent behaviour.
