His lawyers in their motion Friday made several arguments: the prosecution’s legal theories as to what constitutes crimes in the case are unsustainable and have divided other judges; he was not involved in a conspiracy as claimed by the government because he had no contact with other parents charged in the case; relevant evidence that might have favored their client was excluded at trial; and their client is not a flight risk.

“In short, Mr. Wilson’s appeal presents a host of complex and unresolved issues that may well lead to an acquittal, a new trial or a partial quash resulting in a materially shorter sentence,” they wrote in the request.

A spokesperson for the U.S. Attorney’s Office declined to comment.

The defense motion questions whether Wilson’s payments should even be considered bribes.

“Government alleges Mr. Wilson committed a ‘bribe’, under the Honest Services Act, by seeking to donate to university athletic programs in purported exchange for the admission of his children …but there is no precedent for treating as a ‘bribe’ a payment to the institution that is the alleged victim of the offence,” the filing states.

The motion also questioned whether Wilson should have been convicted of wire fraud.

While the prosecution said Wilson’s actions constituted mail or wire fraud because he sought “properties” in the form of “admission slots”, his attorneys argued in the motion that ” offers of admission do not exhibit typical property characteristics and have not historically been treated as property”.

The petition also states that evidence that University of Southern California officials routinely consider financial donations when admitting athletic applicants, including as practice players and for non-athlete roles , was excluded by the court.

In addition to the 15-month prison sentence, Wilson was also ordered to serve two years of probation, perform 400 hours of community service, pay a $200,000 fine and pay $88,546 in compensation to the IRS.

After his sentencing, Wilson’s attorneys appealed for clemency, citing numerous letters of support from friends, including members of the Kennedy clan. Edward M. Kennedy Jr., the son of the late Massachusetts senator, and Kerry Kennedy, daughter of Robert F. Kennedy, said they had known Wilson for years as a neighbor in Hyannisport on Cape Cod.

Wilson remains free and no prison declaration date has been set.

Dozens of famous and wealthy parents, along with a dozen college coaches and sports administrators, have been charged in the conspiracy, which involved payments to get undeserving children into elite American universities with rigged test scores or inflated athletic achievements.

The alleged ringleader was William “Rick” Singer, a college admissions consultant, who pleaded guilty and is cooperating with the government investigation, prosecutors said. At trial, Wilson insisted he had no idea Singer was using his money as kickbacks and falsifying or exaggerating sports credentials on behalf of his children.

Most of the other defendants have already pleaded guilty to the scheme and served their sentences. ‘Desperate Housewives’ star Felicity Huffman has been sentenced to 14 days in jail. ‘Full House’ star Lori Loughlin was sentenced to two months and her fashion designer husband Mossimo Giannulli was sentenced to five months.
