An Adelaide man jailed for choking his former girlfriend with her own hijab has been refused permission to appeal his sentence.
Qasem Gardi, 20, was jailed in December for 11 years and six months for brutally attacking the 18-year-old woman in his car in October 2014.
In the South Australian Supreme Court on Monday, defence lawyer Ahura Kalali said the "manifestly excessive" minimum six-year jail term did not take Gardi's prospects for rehabilitation into sufficient account.
He said Gardi's Iranian ethnicity should be taken into account when considering his controlling behaviour over his former partner.
"I'm saying it may serve to explain some of the things he did," Mr Kalali told the court.

Mr Kalali also noted Gardi's youth and lack of prior convictions.
But judge Trish Kelly rejected Gardi's appeal application, saying the sentence reflected the seriousness of his offending.
The court heard during sentencing that Gardi lured the woman into his car on the pretext of returning a chain she had given him.
Once there he refused to let her leave and drove to another location where he used his hands and the hijab to choke the teenager in and out of consciousness.
The woman previously told the court that the incident had left her feeling like an outcast among her peers, constantly judged and gossiped about.
The attack also left her with purple spots on her face and blood around her eyes for a month.
Prosecutor Lucy Boord, opposing the application, said Gardi's behaviour prior to the attack had effectively amounted to stalking.
"To say that this is an isolated incident, with great respect, is simply wrong," she said.
Gardi will be eligible for parole in October 2020.
