MEMORANDUM OPINION & ORDER
Plaintiff Robert J. Hickey (“Hickey”) brings this suit against defendant Charlene Scott (“Scott”) for breach of contract, alleging that Scott failed to pay him the attorneys’ fees to which he was entitled after he successfully represented her in a sexual harassment suit before the Equal Employment Opportunity Commission (“EEOC”). Sсott has counterclaimed, arguing that Hickey committed legal malpractice and breached his fiduciary duties by engaging in unreasonable billing practices. Scott also contends that Hickey violated the applicable standard of care by failing to request Laffey Matrix hourly rates in his pеtition for attorneys’ fees before the EEOC. 1 Presently before the *3 Court are three evidentiary questions with respect to this claim — whether the parties’ experts should be permitted to testify on (1) whether it is a breach of the appropriate standard of care for an eligible attorney not to request Laffey ratеs in his fee petition before the EEOC, and instead request only his lower, contractual hourly rate; (2) whether Hickey satisfied the legal criteria for an award of Laffey rates; and (3) whether Hickey’s failure to petition for Laffey rates was the proximate cause of any injury to Scott. For the reasons explained below, the Court will allow expert testimony on only the first of these three questions.
1. Whether it is a breach of the applicable standard of care for an eligible attorney not to file a fee petition for Laffey rates before the EEOC is a question that the jury must decide, and on which expert testimony is appropriate. Indeed, in the District of Columbia, expert testimony is required to establish the standard of care in legal malpractice cases “ ‘unless the attorney’s lack of care and skill is so obvious that the trier of fact can find negligence as a matter of common knowledge.’ ”
Chase v. Gilbert,
2. The legal criteria for an award of Laffey rates is, however, a matter of law, on which the Court will instruct the jury. And becausе this is a matter of law, experts will
not
be permitted to describe the circumstances under which an attorney is legally eligible for Laffey rates.
See, e.g.,

Legal Malpractice
§ 36:21 (2011 ed.) (explaining that “[bjecause issues of law are for the court, expert testimony [on issues of law] is not admissible”);
CDX Liquidating Trust ex rel. CDX Liquidating Trustee v. Venrock Assocs.,
3. The final, and most difficult, question — whether Hickey’s failure to peti
*4
tion for Laffey rates before the EEOC was the proximate cause of Scott’s injury— presents the so-called “case within a case” problem typical of legal malpractice actions.
See, e.g., Rubens v. Mason,
“[C]ausation is normally a question of fact reserved for the jury.”
Royal Ins. Co. of Am. v. Miles & Stockbridge, P.C.,
*5
Hence, in attorney malpractice cases where causation requires proof of what would have happened in the underlying “case within the case,” courts simply “instruct the jury on the legal aspects of the case,” and then leave it to the jury to decide, based on the law, what a reasonable fact-finder would have concluded if the attorney had not been negligent.
See, e.g., Helmbrecht,
This Court will follow that apprоach here. The jury will be instructed on the applicable law applied in determining an attorney’s entitlement to Laffey rates. The jury will then have to decide, based on the Court’s instruction as to the law and its own assessment of the facts, whether a reasonable EEOC ALJ would have awarded Laffey ratеs if Mr. Hickey had sought them.
The only remaining question then is whether the jury should be assisted by expert testimony in making this determination. Most courts to address the issue have suggested that
“any
affidavit or testimony from an ‘expert’ arbitrator or judge as to what should have happened in the proceeding that is the subject of subsequеnt malpractice litigation is likely more
*6
prejudicial than probative, because the affidavit or testimony would tend improperly to displace the fact-finder in the malpractice ‘case within a case.’ ”
See Rubens,
This Court agrees. Here, neither Kristin Alden (Scott’s expert) nor Joel Bennett (Hickey’s expert) will be allowed to “invaden the jury’s function” by reaching “the ultimate question” of whether a petition for Laffey rates before a “reasonable ALJ” would have been successful, if such a petition had been made.
See Piscitelli,
The Court recognizes that there is a fine line between expert testimony on
why
Hickey’s failure to petition for Laffey rates constituted a breach of the standard of care (which is permissible) and expert testimony on whether a reasonable ALJ would have awarded Laffey rаtes if Hickey had sought them (which is not permissible). For example, Alden will be permitted to testify that, based on her experience before the EEOC, she believes Hickey breached the applicable standard of care by failing to petition for Laffey rates because it is common praсtice for attorneys in EEOC proceedings to request and receive Laffey rates.
See generally Diamond v. Sokol,
Civ. A. No. 05-4993,
Accordingly, it is hereby ORDERED that
(1) The parties’ experts, Kristin Alden and Joel Bennett, shall be permitted to testify on whether it is a breach of the appropriate standard of care for an eligible attorney not to file a fee petition for Laffey rates before the *7 EEOC in the circumstances presented here;
(2) The experts will not be permitted to testify as to whether Hickey satisfied the legal criteria (as set by the Court) for an award of Laffey rates; and
(3) The experts will not be permitted to testify as to whether Hickey’s failure to petition for Laffey rates was the proximate cause of Scott’s injury, i.e., whether a reasonable ALJ would have awarded Laffey rates if they had been sought.
SO ORDERED.
Notes
. The "Laffey Matrix” is compiled by the Office of the United States Attorney for the District of Columbia, and establishes a market rate for employment attorneys of various experience levels for particular "billing” years. It is used in statutory fee-shifting cases and has its origin in the decision in
Laffey v. Nw. Airlines, Inc.,
. Because the Court’s subject-matter jurisdiction is based on diversity of citizеnship, District of Columbia law applies.
See, e.g., Baker v. Gurfein,
. Because the District of Columbia "derives its common law from the state of Maryland,” courts applying D.C. law may look to Maryland law when there is no controlling D.C. authority directly on point.
Johnson v. Fairfax Vill. Condo. IV Unit Owners Ass’n,
. The exception to this rule occurs when the issue of proximate cause turns on a question
*5
of law. For example, when a plaintiff sues her attorney for legal malpractice based on the attorney's alleged failure to perfect an appeal, "[t]he trial judge ... decides the issue of proximate cause as a matter of law.”
