The Pakistan Cricket Board (PCB) said on Sunday that former Supreme Court judge Justice Faqir Muhammad Khokhar would hear the appeal.
Announcing the appointment, the PCB said: "The independent adjudicator will now decide on the date of the appeal hearing. As soon as this is confirmed, the PCB will make the announcement."
Akmal was issued with his ban from all cricket in April, after two alleged breaches of the PCB's anti-corruption code.
The limited-overs specialist, now 30, was accused of "failing to disclose to the PCB vigilance and security department (without unnecessary delay) full details of any approaches or invitations received by the participant to engage in corrupt conduct under this anti-corruption code".
Akmal, who was provisionally suspended on February 20, could have faced a lifetime ban.
The batsman has played 121 ODIs and 84 Twenty20 Internationals, also featuring in 16 Tests between 2009 and 2011.
Meanwhile, the PCB waved goodbye to several leading figures from within its ranks on Sunday, amid a slew of personnel changes within the organisation and the national cricket academy.
"Mudassar Nazar, Haroon Rashid, Mushtaq Ahmed and Agha Zahid finish their innings at the PCB today," the board said on Twitter.
"While the PCB thanks and wishes them well, it also welcomes Nadeem Khan, Saqlain Mushtaq, Grant Bradburn and Asser Malik."
The PCB on Thursday revealed that Pakistan wicketkeeper-batsman Akmal has been suspended under article 4.7.1 of its code, but did not state the nature of the alleged offence.
Akmal's ban was imposed on the day he was due to play for defending champions Quetta Gladiators in the first game of the Pakistan Super League against Islamabad United.
The 29-year-old has been replaced in the Gladiators squad by Anwar Ali, with an investigation ongoing.
Akmal was this month reprimanded by the PCB after allegedly exposing himself while undergoing a fitness test at the National Cricket Academy.
That incident, which is reported to have seen Akmal ask a trainer "where is the fat?" during a skin-fold test, was described by the PCB as a "misunderstanding".
Akmal has played 121 ODIs and 84 Twenty20 Internationals, also featuring in 16 Tests between 2009 and 2011.
The batsman faced a hearing in Lahore on Monday over two alleged breaches of the PCB's anti-corruption code.
The 29-year-old was accused of "failing to disclose to the PCB vigilance and security department (without unnecessary delay) full details of any approaches or invitations received by the participant to engage in corrupt conduct under this anti-corruption code".
Akmal, who was provisionally suspended on February 20, was facing a maximum of a lifetime ban if found guilty.
The PCB issued a tweet on Monday, confirming: "Umar Akmal handed three-year ban from all cricket by Chairman of the Disciplinary Panel Mr Justice (retired) Fazal-e-Miran Chauhan."
Akmal has played 121 ODIs and 84 Twenty20 Internationals, also featuring in 16 Tests between 2009 and 2011.
The batsman was provisionally suspended from all cricket-related activities on February 20 under article 4.7.1 of the code, but the PCB did not give any further details of alleged wrongdoing.
Akmal has now been deemed to have breached article 2.4.4 in two unrelated incidents.
The 29-year-old has been charged with "failing to disclose to the PCB vigilance and security department (without unnecessary delay) full details of any approaches or invitations received by the participant to engage in corrupt conduct under this anti-corruption code".
Akmal has until March 31 to respond in writing. If guilty, he could be handed a suspension ranging from six months to a lifetime ban.
He has played 121 ODIs and 84 Twenty20 Internationals, also featuring in 16 Tests between 2009 and 2011.
Akmal was punished for two breaches of the PCB's anti-corruption code at a hearing in Lahore on Monday.
The batsman was charged with "failing to disclose to the PCB vigilance and security department (without unnecessary delay) full details of any approaches or invitations received by the participant to engage in corrupt conduct under this anti-corruption code".
Rizvi later revealed that Akmal, who has played for Pakistan 221 times across all formats, showed a lack of remorse.
"He was repeatedly attempting to justify his folly. His reply was confused, he neither accepted his position nor denied it," said Rizvi.
"He did admit the questionable incidents, yet was offering frivolous justifications for non-reporting. When you admit violation, you leave yourself to the mercy of the tribunal.
"There is no general exception in the anti-corruption code that you report on your wish or convenience. You either report or do not report."
He added: "Even today, the honourable judge asked him [Akmal] on a clear note if he accepts his indiscretions, but he insisted on justifying his failures.
"He was charged on two counts, for two different unrelated incidents while Mohammad Irfan [who was suspended for one year] and others had completely different cases.
"Irfan got a lesser ban because he had accepted his mistake and agreed to the imposed sanctions. But Umar Akmal tried to justify why he didn't report.
"This three-year ban on the basis of non-reporting is considered appropriate. The PCB was asking for a stiffer sentence.
"It's high time that duration of the ban should be increased because it's very clear that players are not learning the lessons as much as they should have.
"So as far as the legal side is concerned, I am very satisfied as the duration of the ban is reasonable, justified and proportionate.”
The Pakistan batsman was handed the ban in April after two alleged breaches of the Pakistan Cricket Board's (PCB) anti-corruption code.
Having initially not contested the verdict, he filed an official appeal in May, with former Supreme Court judge Justice Faqir Muhammad Khokhar appointed as an independent adjudicator.
Akmal attended the hearing in Lahore in person as his ban was cut, meaning it will run until August 2021, though the 30-year-old has suggested he will possibly look to have it reduced further.
"I am thankful to the judge for listening to my lawyers properly," Akmal said after the hearing, as reported by ESPNcricinfo.
"I will decide about the remaining sentence and try to get it reduced further. For now, I am not satisfied and will consult my lawyers and family how to take this ahead.
"There are many players before me who made mistakes and just look at what they got and what I got. So all I say right now is thank you very much."
Akmal has played 121 ODIs and 84 Twenty20 Internationals, also featuring in 16 Tests between 2009 and 2011.
The batsman was charged with two alleged breaches of rules set out in the Pakistan Cricket Board (PCB) anti-corruption code in two unrelated incidents.
The 29-year-old is accused of "failing to disclose to the PCB vigilance and security department (without unnecessary delay) full details of any approaches or invitations received by the participant to engage in corrupt conduct under this anti-corruption code".
Akmal, who was provisionally suspended on February 20, could face a lifetime ban if found guilty.
He did not request a hearing before the anti-corruption tribunal after being charged with breaches of article 2.4.4 of the PCB code.
Akmal has played 121 ODIs and 84 Twenty20 Internationals, also featuring in 16 Tests between 2009 and 2011.
