However, questions were raised over whether the case could have been tried in a higher court.
First Minister Alex Salmond said the maximum sentence was justified, but Willie Rennie of the Liberal Democrats called on the Crown Office to review how it handles such cases. Ruth Davidson of the Conservatives agreed, while Labour said a fortnight in prison per crime could not be right.
Diana Walker's brother-in-law Rob Armstrong, who warned the SNP about Walker's character years before he was elected, welcomed the sentence and said the former MSP "got what he deserved".
Detective Superintendent Stuart Johnstone of Police Scotland praised the bravery of Walker's victims, adding: "Police Scotland and its partners are committed to providing a consistent and professional approach to domestic abuse."
In Dunfermline High Street there was little sympathy for their former MSP, with women in particular, most of them reluctant to be named, saying he had got what he deserved.
Bruce Whyte, a college lecturer, said it would have sent out the wrong message about domestic abuse if he had not been sent to prison and the outcome would be a positive one for his victims. His wife Susan, who works in a pharmacy, agreed, saying: "It doesn't seem a long sentence but if it's the maximum then I can understand that."
The phrases "he got what he deserved" and "no excuse" were recurring opinions and Correen Dickson, 26, said his victims had suffered for far longer than the year he was sentenced to. But Kelly Wilton offered another view. "I am not condoning domestic abuse in any way, but I think he was sentenced for who he was rather than what he did. Most men who commit domestic violence walk away with a fine or a suspended sentence. I'm not saying that's right, but he has been treated differently."
