OPINION
PER CURIAM.In this matter, Steven E. Ferrey, Esquire, a member in good standing of the Massachusetts bar, has moved for pro hac vice permission to provide legal services to a client in a continuing administrative proceeding before a state agency. He has done so pursuant to Article II, Rule 9 of our Supreme Court Rules. Based upon the contents of the affidavit filed as part of his motion, we grant that part of his motion seeking permission to practice before the Energy Facility Siting Board, effective as of the date of this opinion. We deny, however, that part of his motion seeking our permission, nunc pro tunc, to the date of his first appearance before that state agency, and we deem it advisable at this time to give our reasons for so doing.
We begin by noting that this Court never before, in any published opinion or order, has granted a pro hac vice request nunc pro tunc when to do so “would be tantamount to affixing an ex post facto imprimatur of approval on what might under some circumstances be construed as the unauthorized practice of law[,]” a criminal offense prohibited by G.L.1956 § 11-27-5. In re Church, 111 R.I. 425, 427, 303 A.2d 758, 759 (1973). See also In re Olsen, 112 R.I. 673, 674, 314 A.2d 140, 141 (1974).1
Since 1917, § 11-27-5 has provided that:
“No person, except a member of the bar of this state, whose authority as a member to practice law is in full force and effect, shall practice law in this state.”
The practice of law is defined in § 11-27-2 as:
“the doing of any act for another person usually done by attorneys at law in the course of their profession, and, without limiting this generality, includes:
(1) The appearance or acting as the attorney, solicitor, or representative of another person before any court, referee, master, auditor, division, department, commission, hoard, judicial person, or body authorized or constituted by law to determine any question of law or fact or to exercise any judicial power, or the preparation of pleadings or other legal papers incident to any action or other proceeding of any kind before or to be brought before the court or other body[.]” (Emphasis added.)
Recognizing that circumstances might arise when a particular client might on *64“special and infrequent occasion and for good cause shown” require the assistance of an out-of-state attorney in a particular court proceeding in this state, this Court promulgated Rule 9 of Article II of our Supreme Court Rules concerning the admission of out-of-state counsel to practice law in this state.
It is important for the bar, as well as the various state agencies, boards and commissions, to note that Rule 9 pertains only to the granting of pro hac vice permission by this Court for an out-of-state attorney to represent a client in a cause or appeal “in any court of this state.” There is nothing in Rule 9 that makes reference for admission pro hac vice of an out-of-state attorney to practice law here before any state or municipal board, agency or commission. That omission in Rule 9, however, does not deprive us of our unquestioned inherent right to permit an out-of-state attorney to do so upon a timely pro hac vice request by out-of-state counsel. In that regard, this Court recognizes full well that “ ‘[practice of law under modern conditions consists in no small part of work performed outside of any court and having no immediate relation to proceedings in court.’ ” Rhode Island Bar Association v. Automobile Service Association, 55 R.I. 122, 134, 179 A. 139, 144 (1935).
Consequently, because this Court has exclusive and ultimate authority to determine who may, and may not be permitted to practice law in this state, see Unauthorized Practice of Law Committee v. State, Department of Workers’ Compensation, 543 A.2d 662, 664 (R.I.1988), we may, on proper motion, permit pro hac vice approval to an out-of-state attorney to practice law in this state before a municipal or state agency, board or commission. However, that permission can come only from this Court and, absent such prior permission, an out-of-state lawyer is subject to the prescriptions of § 11-27-5, as set out above.
We point out that § 11-27-6 also prohibits any out-of-state lawyer who practices law here without this Court’s prior pro hac vice permission from receiving “any pay or compensation, directly or indirectly * * * for any services of a legal nature * * * pertaining to any action or proceeding in any court or before any referee, master, auditor, commission, division, department, board, or other judicial person or body, or for the preparation of any legal instrument[.]” Section 11-27-14 provides criminal penalties, both misdemeanor and felony, for violations of the prohibitions contained in chapter 27 of title 11, and, § 11-27-19 imposes upon the Attorney General the duty to prosecute or to restrain and enjoin any such violations. Whether Ferrey’s past appearances before the Energy Facility Siting Board constitutes unauthorized practice of law in violation of chapter 27 of title 11 is not before us in this proceeding. Notwithstanding, the dissent suggests that § 11-27-13 might shield Ferrey from possible violation and prosecution. That suggestion, it must be noted, even if correct, overlooks the fact that § 11-27-13 does not extend to § 11-27-3, and thus, if Ferrey were to receive any fee for his services, he would then be in clear violation of chapter 27 of title 11 and subject to possible criminal prosecution, pursuant to § 11-27-19, or by private criminal complaint.
Thus, it is abundantly clear that since 1917, chapter 27 of title 11 has made unlawful the practice of law in this state by any lawyer who is not a member of the Rhode Island bar and who has not been given prior pro hac vice permission to practice here, regardless of whether that attorney appears before any court or before any municipal or state agency, board *65or commission. This Supreme Court alone possesses sole authority to determine who may, and who may not, engage in the practice of law in this state. No municipal or state board, agency or commission shares in that authority, and none has ever been delegated by this Court to any municipal or state board, agency or commission.
In the particular matter before us concerning Attorney Ferrey, his motion request for pro hac vice admission was made in the alternative; namely, he requested admission at this time, and/or that such admission be made nunc pro tunc because he had in fact been practicing law here in this state before the Energy Facility Siting Board in apparent violation of § 11-27-5. However, he had done so with the agency’s specific, but unauthorized, permission.
Attorney Ferrey, like everyone else in this state, is presumed to know what the laws of this state permit and prohibit. However, as a nonresident who had been given permission, albeit unauthorized, to practice in this state, it is somewhat understandable that Attorney Ferrey might not have known that chapter 27 of title 11 of our General Laws prohibited his practice before the particular state agency when he initially appeared.2 That assumed absence of knowledge, coupled with the Energy Facility Siting Board’s previous permission for him to appear before it based upon its mistaken belief that it had been delegated authority to do so, prompted our decision to grant his pro hac vice request for permission to continue to represent his client in the continuing legal proceedings before that board. Our reason for declining his nunc pro tunc request is because, as noted earlier, “[t]o do so would be tantamount to affixing an ex post facto imprimatur of approval on what might under some circumstances be construed as the unauthorized practice of law” in violation of § 11-27-5. In re Church, 111 R.I. at 427, 303 A.2d at 759. See also In re Olsen, 112 R.I. at 674, 314 A.2d at 141. Thus, while Attorney Ferrey may be excused for not being aware of our state laws, this Court, on the other hand is presumed to know what § 11-27-5 prohibits, and we are duty bound to follow that law and not blindly ignore or condone past transgressions thereof.3
. The dissent attempts to shunt the reality of the cold fact that this Court has never in any previous published opinion or order ever granted a pro hac vice request nunc pro tunc by divergently suggesting that such lack of precedent tells us little or nothing about the Court’s past practice in this respect. It is for that very reason that a majority of this Court now issues this opinion and reiterates what it spoke of in both In re Church, 111 R.I. 425, 303 A.2d 758 (1973) and In re Olsen, 112 R.I. 673, 314 A.2d 140 (1974).
. Attorney Feriy is a member of the Massachusetts Bar. We note here that the Supreme Judicial Court of Massachusetts previously has stated that:
"[t]he judicial department of government, and no other, has power to license persons to practice law. Statutes may aid by providing machinery and criminal penalties, but may not extend the privilege of practis-ing law to persons not admitted to practice by the judicial department.” Lowell Bar Association v. Loeb, 315 Mass. 176, 52 N.E.2d 27, 30 (1943).
. The concern expressed in the dissent about the lack of any rules governing a nonresident attorney’s right to practice before an "in state commission” is answered by G.L.1956 §§ 11-27-2 and 11-27-5 of our general laws.
Because, as yet, there has been no formal adjudication by any court of a criminal violation of chapter 27 of title 11 on the part of Attorney Ferrey, a viable option to criminally prosecute pursuant to that statute still remains a consideration for the Unauthorized Practice of Law Committee; the Attorney General; or conceivably for a private complainant. For that reason alone, for this Court to have granted Attorney Ferrey’s nunc pro tunc permission request would have been "tantamount to affixing an ex post facto imprimatur of approval” and the sanctioning of what appears to have been the illegal practice of law here by an out-of-state attorney who is not a member of the Rhode Island Bar. In re Olsen, 112 R.I. at 674, 314 A.2d at 141.
