A statement from the Attorney General's Office said:
Having carefully reviewed this case, the Attorney General, Dominic Grieve QC MP, has decided to refer the sentence of Neil Wilson to the Court of Appeal for review.
The case will in due course be heard by three Court of Appeal judges who will decide whether or not the sentence is unduly lenient and whether they should increase it.
Robert Colover has been suspended from prosecuting sexual offence cases pending a review by the Crown Prosecution Service (CPS), while Judge Peters' comments are to be investigated by the Office for Judicial Complaints.
As well as receiving a number of complaints, the CPS was confronted by a petition, which now has more than 50,000 signatures, demanding Director of Public Prosecutions Keir Starmer investigate the language used by Mr Colover.
The Attorney General's Office has confirmed that the case has been referred and is being considered to see if it will be taken to the Court of Appeal as 'unduly lenient.'
The case has been drawn to the attention of this office as a possibly unduly lenient sentence.
This means it'll be considered by a law officer (the Attorney or Solicitor General) who will decide whether it should be referred to the Court of Appeal under the Unduly Lenient Sentence (ULS) scheme.
The law officers have 28 days to make their considerations, this office will ask the CPS for more information on the case (trial papers, files etc) and the decision will be announced once all the information has been considered.
In evidence presented to the court during his trial, convicted paedophile 41-year-old Neil Wilson admitted inviting the 13-year-old back to his house after she asked him to buy her cigarettes but denied they had intercourse.
Wilson admitted the pair called and texted each other over a period of two weeks but also claimed he told her he had to stop seeing her as they would get into trouble.
Wilson claimed she undressed and began kissing him before touching his genitals. He also said he pushed her away and denied that sexual intercourse took place.
Leading human rights barrister John Cooper said it was important to look into the reasons why the prosecutor and judge labelled a 13-year-old child sex abuse victim as "predatory," taking into consideration the language of the police and the CPS.
Speaking to ITV News he said the criminal justice system was working hard to make it easier for victims of sexual abuse to come forward, and that instances like this "set the clock back."
