CHOY, Circuit Judge:
I. BACKGROUND
A.
Petitioner Emil Lawrence, who is registered with the Commodity Futures Trading Commission (“the Commission”) as an associated person (“AP”) of a commodity broker, was a respondent in an earlier Commission enforcement proceeding,
In re First Commodity Cory, of Boston,
CFTC Docket No. 79-28. On September 3, 1980, Lawrence agreed to a settlement in that proceeding. He consented to findings that he had violated antifraud provisions of the Commodities Exchange Act, 7 U.S.C. §§ 1-26 (1980) “the Act”, relating to transactions in commodity options, and agreed to pay a civil penalty of 13,500.
Finding this settlement acceptable, the Commission on October 15, 1980 entered an order imposing a $3,500 civil penalty against Lawrence, payable six months later on April 15, 1981.
The instant petition for review arises from a disciplinary proceeding conducted by the Commission pursuant to sections of the Act, 7 U.S.C. §§ 9,12a(3), and 13(b). In this proceeding the Commission determined that Lawrence had willfully violated its previous order to pay the civil penalty assessed against him. For this willful violation, the Commission suspended Lawrence’s AP registration for three months.
Lawrence appeals his suspension.
B.
The administrative complaint served upon Lawrence on December 9, 1981 charged that he was unfit to remain registered as an AP of a commodity broker
because he had violated the Commission’s October 15, 1980 order to pay the $3,500 civil penalty. Pursuant to the Act,
the Commission sought to determine whether it should revoke Lawrence’s AP registration, suspend his contract market trading privileges, or enter a cease and desist order.
The complaint at issue here was the subject of a hearing before Administrative Law Judge (“AU”) George Painter. The AU found that Lawrence did not pay the $3,500 penalty when it came due on April 15, 1981; that the Commission’s Division of Enforcement notified Lawrence by letter dated May 7, 1981 that the penalty had become due; that Lawrence made no written request to the Division for an extension of time in which to pay the penalty between April 15 and December 9, 1981, when the second complaint was served; that Lawrence spoke with no responsible Division official between April 15 and December 9, 1981 concerning his alleged inability to pay the penalty; that Lawrence had not paid the penalty when the second proceeding was commenced; and that any efforts by Lawrence to resolve the matter before issuance of the second complaint “were half-hearted at best.”
Concluding that Lawrence had violated the Commission’s order to pay his penalty,
the ALJ directed him to pay the $3,500 civil penalty, with interest, within ten days, and also imposed an additional $500 penalty for the violation.
The Commission, following an independent review of the record, in part reversed the decision of the AU. The Commission concluded that Lawrence’s violation of its order to pay the $3,500 on April 15, 1981 had been willful, and suspended his AP registration for three months.
The Commission based its determination on uncontroverted evidence that Lawrence was aware that payment was due on April 15, 1981; that he failed to pay the penalty when due; that he never made a written request for an extension of time in which to pay; that he never responded in writing to a warning letter sent to him by the Commission on May 7, 1981; and that he never tendered even partial payment until after the enforcement complaint was filed, more than seven months after payment had come due. The Commission’s January 31, 1984 Order provided that Lawrence’s suspension would not take effect until 30 days after service so as to give Lawrence an opportunity to wind down his affairs in an orderly fashion.
II. ISSUES
This appeal presents three issues, the first and third being questions of first impression.
1. Did the the Commission have jurisdiction under § 6(b) of the Commodity Exchange Act to bring an independent enforcement proceeding against Lawrence for his failure to timely pay the consented-to civil penalty?
2. Did the weight of the evidence support the Commission’s finding that Lawrence’s violation of its order to pay the penalty was willful?
3. Was the Commission’s decision to suspend Lawrence’s AP registration for three months so severe that it should be set aside as an abuse of discretion?
III. DISCUSSION
A. Jurisdiction
Lawrence contends that pursuant to 7 U.S.C. § 9 and 28 U.S.C. § 1355, the Commission’s only remedy for his violation of its 1980 order to pay the civil penalty was to refer a collection action to the Department of Justice. He argues that the Commission lacked jurisdiction to bring the second, independent enforcement action.
28 U.S.C. § 1355 gives the district courts original jurisdiction over court actions brought to reduce fines to judgment. 7 U.S.C. § 9a provides that collection of overdue money penalties imposed by the CFTC shall be referred to the Attorney General for recovery in a federal district court action. The Commission, however, also has the authority to suspend or revoke the registration of any person it finds to have violated any of its orders. 7 U.S.C. § 9,
see supra,
note 6.
Nothing in the language of § 9 suggests that the Commission’s authority to bring an action seeking suspension is limited to violations of particular kinds of Commission orders. We conclude that the broad reference in § 9 to “any” Commission order includes the order to Lawrence to pay his monetary penalty.
Likewise, 7 U.S.C. §§ 12a(3)-(4) expressly empowers the Commission to suspend or revoke the registration of anyone found to have violated any provision of the Act or
order thereunder. Congress repeated verbatim in § 12a(3) the broad language used in § 9, again without any suggestion that the Commission’s authority to suspend or revoke registration hinges on the particular type of Commission order violated.
The Commission argues that although 7 U.S.C. § 9a limits its collection remedy to referral to the Justice Department, Lawrence’s failure to pay the $3,500 penalty constituted a discrete violation of a Commission order, cognizable under 7 U.S.C. § 9.
The Commission’s interpretation of its authority under the Act deserves substantial deference. The Supreme Court has repeatedly declared that “great deference [should be given] to the interpretation given the statute by the officers or agency charged with its administration.”
Udall v. Tollman,
380 U.S. 1, 16, 85 S.Ct. 792, 801, 13 L.Ed.2d 616 (1965).
Recently, the Supreme Court reemphasized the narrowness of a court’s inquiry in reviewing an agency’s interpretation of its empowering act. When the legislature has left a gap in a statute as to the details of its administration, “a court may not substitute its own construction of a statutory provision for a reasonable interpretation made by the administrator of an agency.”
Chevron, U.S.A., Inc. v. Natural Resources Defense Council,
— U.S. -,-, 104 S.Ct. 2778, 2782, 81 L.Ed.2d 694 (1984) (citations omitted).
Nothing in 7 U.S.C. § 9a or 28 U.S.C. § 1355 suggests that Congress intended referral to the Department of Justice to be the Commission’s exclusive remedy for violation of its orders to pay fines. The more reasonable interpretation is that Congress did not intend such exclusivity, since 7 U.S.C. §§ 9, 12a(3)-(4) expressly provide for other, noncollection remedies for violations of any Commission order.
The Commission’s interpretation of its powers is also consistent with the Federal Claims Collection Act of 1966, 31 U.S.C. §§ 3701, 3711, 3718-19
(as amended by
Debt Collection Act of 1982, Pub.L. No. 97-365, 96 Stat. 1749 (1982)) (“FCCA”). The legislative history of the FCCA expressly reflects Congress’s stated preference for the handling of agency claims by the agency involved.
The provisions of the FCCA and the amendments in the Debt Collection Act of 1982 express a Congressional mandate that agencies play a more active role in the collection of delinquent claims than merely referring them to the Department of Justice.
We hold that the Commission had jurisdiction to bring a second action seeking sanctions for Lawrence’s violation of its payment order.
B. Willfulness
Although Lawrence concedes that he never attempted to pay the overdue $3,500 penalty until the Commission complaint placed his AP registration in jeopardy, he attacks the Commission’s conclusion that his failure to pay was willful. Instead, he characterizes his prolonged, knowing failure to pay as “negligent.”
The standard of review applicable here is set forth in 7 U.S.C. § 9: “the findings of the Commission as to the facts, if supported by the weight of evidence, shall ... be conclusive.” The phrase “weight of evidence” in 7 U.S.C. § 13a has been interpreted to mean “ ‘the preponderance’ or ‘greater weight of the evidence.’ ”
Myron v. Hauser,
673 F.2d 994, 1005 n. 17 (8th Cir.1982) (quoting
Haltmier v. CFTC,
554 F.2d 556, 560 (2d Cir.1977)).
Lawrence admits that he was aware that his fine had fallen due on April 15, 1981. Despite doubts about his ability to pay the fine as far back as September 1980 when he first agreed to it, Lawrence admittedly never made a written request for an extension of time; nor did he speak with any responsible official at the CFTC’s Division of Enforcement. Moreover, Lawrence admits that he never responded in writing to the Commission’s warning letter of May 7, 1981.
He did not even tender partial payment during the eight months of his delinquency leading up to the issuance of the second complaint.
Lawrence does not dispute these facts. Instead he argues that his conduct was merely negligent. For purposes of the Act, however, it is well settled that:
[i]f a person 1) intentionally does an act which is prohibited, — irrespective of evil motive or reliance on erroneous advice, or 2) acts with careless disregard of statutory requirements, the violation is willful.
Flaxman v. CFTC,
697 F.2d 782, 787 (7th Cir.1983) (quoting
Goodman v. Benson,
286 F.2d 896, 900 (7th Cir.1961)). To establish willfulness, the Commission only needed to show that Lawrence’s ongoing failure to act was intentional as opposed to accidental. Proof of an evil motive is unnecessary.
See Hinkle Northwest, Inc. v. SEC,
641 F.2d 1304, 1307-08 (9th Cir.1981) (quoting
Nees v. SEC,
414 F.2d 211, 221 (9th Cir.1969)). We agree with the Corn-
mission that Lawrence’s inaction was willful.
Lawrence argues that the Commission’s willfulness conclusion should be reversed because it failed to give proper deference to the ALJ’s first-hand assessment of Lawrence’s credibility. But the Commission gives less deference to an ALJ’s findings on ultimate questions of fact, and it also need not hesitate to overrule an ALJ’s finding if his analysis of the evidence is “logically unsound.”

aff'd mem.,
No. 78-3581 (6th Cir.1981);
see also Pierce v. SEC,
239 F.2d 160, 162-63 (9th Cir.1956). In
Moore v. Ross,
687 F.2d 604, 607-09 (2d Cir.1982),
cert. denied,
459 U.S. 1115, 103 S.Ct. 750, 74 L.Ed.2d 969 (1983), the court held that credibility determinations are questions of fact within an agency’s province and that the agency’s resolution of them contrary to the ALJ’s must stand unless it is not supported by substantial evidence.8 *****
Given these standards, we affirm the Commission’s finding of willfulness. Lawrence’s failure to take any meaningful action between April 15 and December 3, 1981 was conscious and it was intentional.
C. The Discretionary Suspension
Lawrence contests as impermissibly severe the Commission’s suspension of his AP registration for three months. Lawrence also maintains that the Commission should not have imposed any sanction because he presented sufficient evidence of mitigation or rehabilitation.
Although authorized to do so under 7 U.S.C. §§ 9, 12a, and 13b, the Commission did not prohibit Lawrence from trading on contract markets, enter a cease and desist order against him, or impose conditions on or permanently revoke his registration. We find that the Commission considered several potential sanctions and imposed one — a three month suspension— that fitted Lawrence’s willful violation and served the public interest.
Choice of sanction here is a matter within the Commission’s sound discretion.
See Silverman v. CFTC,
562 F.2d 432, 439-440 (7th Cir.1977). If within statutory limits, the Commission’s determination will be upheld unless it reflects an abuse of that discretion.

see also Nees v. SEC,
414 F.2d 211, 217 (9th Cir.1969).
The Supreme Court has declared it a: “fundamental principle ... that where Congress has entrusted an administrative agency with the responsibility of selecting the means of achieving the statutory policy ‘the relation of remedy to policy is peculiarly a matter for administrative competence.’ ”
American Power Co. v. SEC,
329 U.S. 90, 112 [67 S.Ct. 133, 146, 91 L.Ed. 103] (1946). Thus, the [Administrator’s] choice of sanction was not to be overturned unless the Court of Appeals might find it “unwarranted in law or ... without .justification in fact....”

411 U.S. 182, 185-86, 93 S.Ct. 1455, 1458, 36 L.Ed.2d 142 (1973). This “fundamental principle” has repeatedly been applied by the Supreme Court, this court and the other federal courts of appeals in upholding sanctions under the Act and other federal remedial regulatory statutes.
See, e.g., Nees v. SEC,
414 F.2d at 217;
Pierce v. SEC,
239 F.2d 160, 163-64 (9th Cir.1956).
In upholding a remedial sanction denying registration to a securities broker, this court articulated the appropriate standard of review for cases of this kind:
Denial of registration is not to be regarded as a penalty imposed on the broker. To the contrary, it is but a means to protect the . public interest____ This
Court ordinarily should not substitute its judgment of what would be appropriate under the circumstances in place of the Commission’s judgment as to measures necessary to protect the public interest____ [W]e cannot conclude that the Commission abused its discretion in denying ... registration.
Pierce,
239 F.2d at 163-64 (citations omitted).1 *************
The standard for suspension of a registration already granted is similar. Once a willful violation of the Commission’s 1980 order had been proved, a
prima facie
case of Lawrence’s unfitness to remain registered as an AP was established and the statutory basis under the Act to revoke Lawrence’s registration was met.
See In re Tipton,
[1977-80 Transfer Binder] Comm.Fut.L.Rep. (CCH) 1120,673.
The three month suspension here meets these settled standards. Well within the limits authorized by statute, the suspension was neither “unwarranted in law” nor “without justification in fact.”
1.
Mitigation and Rehabilitation
Even though the Commission established a prima facie case of Lawrence’s unfitness for continued registration, it could have chosen not to suspend Lawrence’s registration if he had shown, through evidence of mitigation or rehabilitation, that the public interest would not be served.
See Savage v. CFTC,
548 F.2d 192, 196-97 (7th Cir.1977);
In re Tipton,
[1977-80 Transfer Binder] Comm.Fut.L.Rep. (CCH) at 22,750. But the burden on Lawrence to persuade the Commission that he should receive no registration sanction was substantial.
See Flaxman v. CFTC,
697 F.2d at 788-89;
Savage,
548 F.2d at 196-97.
In arguing mitigation, Lawrence asserted that he had lacked the funds to timely pay the penalty. He testified that the $6,000 he spent on attorney’s fees in the original action rendered him unable to pay the penalty agreed to in settlement of that action.
Lawrence has provided no explanation for his decision to subordinate the Commission’s payment order to his other financial obligations. His speedy tendering of payment in an attempt to settle this proceeding, once it was commenced, belies his claimed inability to comply. Lawrence’s intentional inaction until faced with the second proceeding shows indifference toward the Commission’s 1980 payment order and disrespect for the Commission. Lawrence failed to carry the heavy burden of demonstrating mitigation.
As for rehabilitation, Lawrence argues that except for his failure to pay the penalty (and for the underlying findings against him as set forth in the 1980 payment order), he did not otherwise violate the Act or the Commission’s regulations. Lawrence also argues that his offer to settle the second complaint by paying the overdue $3,500 demonstrated rehabilitation.
The Commission determined below and argues here, however, that while Lawrence’s late offer of payment may have obviated the permanent revocation of his registration, it was not sufficient to assure the Commission that he had gained respect for his duty to abide by the requirements of the Act. The Commission therefore concluded that Lawrence had not demonstrated rehabilitation sufficient to warrant no registration penalty.
We will not disturb an administrative determination of this kind unless the Commission abused its discretion.
See Silverman v. CFTC,
562 F.2d 432, 439 (7th Cir.1977). Contrary to his assertion, the Commission did not give “short shrift” to Lawrence’s rehabilitation evidence. Although it was within the Commission’s sound discretion not to consider such evidence, it chose, over the objections of its Division of Enforcement, to consider all the rehabilitation evidence presented.
Reviewing the evidence, we conclude that Lawrence has not demonstrated that the Commission abused its discretion. Neither his tender of payment after commencement of the second proceeding, nor his refraining from further offenses, is sufficiently probative. We conclude that the suspension was specifically authorized by the Act, was warranted in fact, and was within the Commission’s statutory discretion.
2.
Severity
Lawrence argues that his three-month suspension was too severe because this case represents the Commission’s first administrative action brought for a failure to obey an order to pay a civil penalty, and because he may suffer financial harm from his suspension.
The Commission, “like the SEC in the securities area, is the ‘statutory guardian’ entrusted with the enforcement of the congressional scheme for safeguarding the public interest in commodity futures markets.”
CFTC v. British American Com-modify Options Corp.,
560 F.2d 135, 142 (2d Cir.1977),
cert. denied,
438 U.S. 905, 98 S.Ct. 3123, 57 L.Ed.2d 1147 (1978).
The Commission concluded that the circumstances of Lawrence’s willful violation of its payment order raised substantial questions about his respect for the Commission’s enforcement program. By imposing the suspension, the Commission sought to impress upon Lawrence and other registrants that they cannot ignore Commission orders, wait for the Commission to proceed administratively against them, and only then, if necessary, bring themselves into compliance with impunity.
Lawrence characterizes his suspension as “a novel move by the CFTC,” and it is true that this was the first proceeding brought for failure to obey a Commission order to pay a civil penalty. A sanction, however, is “not rendered invalid in a particular case because it is more severe than sanctions imposed in other cases.”
Sartain v. SEC,
601 F.2d 1366, 1374-75 (9th Cir.1979) (quoting
Butz v. Glover Livestock Commission Co.,
411 U.S. 182, 187-88, 93 S.Ct. 1455, 1458-59, 36 L.Ed.2d 142 (1973)).
Deterrence is a permissible function of the Commission’s disciplinary sanctions.
Steadman v. SEC,
603 F.2d 1126, 1142 (5th Cir.1979),
aff’d on other grounds,
450 U.S. 91, 95, 101 S.Ct. 999, 1004, 67 L.Ed.2d 69 (1981). We conclude that Lawrence’s three-month suspension was not improper because of its novelty, nor was it unduly severe.
We affirm the Commission’s January 81, 1984 Opinion and Order. This court’s stay of the three-month suspension is vacated.
