MEMORANDUM OPINION1

1 Rule 10 of the Rules of the Court of Appeals of Tennessee provides:

This Court, with the concurrence of all judges participating in the case, may affirm, reverse or modify the actions of the trial court by memorandum opinion when a formal opinion would have no precedential value. When a case is decided by memorandum opinion it shall be designated “MEMORANDUM OPINION,” shall not be published, and shall not be cited or relied on for any reason in any unrelated case. I. FACTUAL AND PROCEDURAL BACKGROUND

In August 2010, Plaintiff/Appellant Abdoulaye Mamadou (“Appellant”) hired Defendant/Appellee law firm Gatti, Keltner, Bienvenu & Montesi, P.C. (“Appellee”) to handle a workers’ compensation claim against Appellant’s employer, Harrah’s Casino, in Mississippi. Attorney David Reid Wamble primarily handled the case.

A trial before an administrative judge occurred in which Appellant was awarded wage-loss benefits in the total amount of $101,501.05. Harrah’s Casino appealed the judgment to the Mississippi Workers’ Compensation Commission (“MWCC”), which resulted in Appellant’s award slightly increasing to $102,153.56 by order of October 11, 2016. The final sentence of the MWCC order stated that Appellant’s “matter is remanded to the Administrative Judge for all further proceedings as may be necessary in this claim.”

The monetary award was disbursed on or about December 1, 2016. Appellee was paid twenty-five percent of the award plus expenses, pursuant to the parties’ contract. On December 1, 2016, Appellant executed a two-page “Authorization” detailing the expenses and attorney’s fees that were associated with the representation and that would be deducted from the award, which the parties appear to refer to as a “Disbursement Sheet.” The Disbursement Sheet states that Appellant “understand[s] and approve[s] the [] settlement disbursements and acknowledge[s] the settlement and disbursements are in accord with [his] instructions and understanding.” On the same day, Appellant also executed a document titled “Authority to Settle and Affidavit” in which Appellant affirmed the following:

I am completely satisfied with the professional services rendered by the law firm of [Appellee] and by the law firm of D. Reid Wamble, Attorney at Law, and I authorize and direct the complete settlement of my case. I have no reservations whatsoever with the acceptance of the final settlement amount of $102,153.56, nor with the disbursement, the amount, or the percentage of the attorney’s fees. Said attorney fees are fair and commensurate with the amount of work that law firm of [Appellee] and the law firm of D. Reid Wamble performed on my case and the amount contracted to between [Appellee] and myself. I certify that there are no other outstanding expenses in this case, but if any other expenses should come to my attention, or to the attention of my attorneys at a later date, I expressly agree to be responsible for their payment thereof and to hold [Appellee] and D. Reid Wamble, Attorney at Law harmless regarding the same.[2] 2 Appellant did not dispute that he signed this form but did dispute that he understood the effect of the form given his limited English proficiency. Still, one of the undisputed material facts that he submitted was as follows: “It is true and correct that when [Attorney] Wamble had [Appellant] sign the Disbursement Sheets, Attorney Wamble did everything to make sure [Appellant], at minimum, fully understood the Disbursement Sheet’s meaning and effect without having a translator.” Again, the Disbursement Sheet and -2- Immediately after December 1, 2016, Appellant began to have concerns that he had not been paid all of the benefits to which was entitled; Appellant promptly communicated his concerns to Attorney Wamble. Attorney Wamble allegedly responded that Appellant had received all that he was entitled to under Mississippi law.

On August 10, 2023, Appellant filed a pro se complaint against Appellee in the Shelby County Circuit Court (“the trial court”). The complaint alleged that Attorney Wamble committed legal malpractice in not pursuing the full amount of workers’ compensation benefits to which Appellant was entitled. As for the specific negligence at issue, Appellant alleged that Appellee, through Attorney Wamble, failed to inform him that the workers’ compensation carrier filed a “B-31 form” in 2019 or that his benefits were terminated as a result of the filing of this form.3 So Appellant contended that Appellee “should have withdrawn from [his] case and allowed [him] to handle it [himself], or even given the option to hire another attorney to do it for [him.]” Rather, Appellee allegedly did not inform Appellant of the filing of this form until 2022. At this point, Appellant contacted the MWCC. According to the complaint, the MWCC advised Appellant that “they could not speak with [Appellant] regarding [his] claim, due to [him] having legal counsel. Because of this, [Appellant] requested that [Attorney Wamble] be withdrawn from [the] case.” Attorney Wamble then formally withdrew from the workers’ compensation action, allowing Appellant “to speak with the insurance carrier, and [he] was then reimbursed for all my medications, which [he] had been complaining about for the last several years.” According to Appellant, however “when [he] filed a motion for reconsideration, [the] request was denied, due to untimely filing . . . . This has caused a tremendous strain on [Appellant], financially[.]”4

the Authority to Settle and Affidavit were signed on the same day. 3 Mississippi law requires that

[w]ithin thirty (30) days after the final payment of compensation has been made, the employer shall send to the commission a notice in accordance with a form prescribed by the commission, stating that such final payment has been made, the total amount of compensation paid, the name of the employee and of any other person to whom compensation has been paid, the date of the injury or death, and the date to which compensation has been paid.

Miss. Code Ann. § 71-3-37(7). Rule 2.17 of the Rules of the Mississippi Workers’ Compensation Commission provides that an “[e]mployer or carrier’s filing of a properly completed Form B-31 shall constitute compliance with the requirements of Miss. Code Ann. Section 71-3-37(7).” The notice is mailed to both the counsel for the claimant and the claimant. Id. A claimant generally has one year from this filing to seek modification of the award on the basis of “a change in conditions or because of a mistake in a determination of fact[.]” Miss. Code Ann. § 71-3-53.
