This case comes to us on appeal from the State Bar Grievance Board (hereafter "Board”). Appellant áttorney, Walter O. Estes, contends both that the facts elicited in hearing panel testimony are insufficient to support a finding of unprofessional conduct, and that, in any case, such conduct as the Board found appellant engaged in does not present grounds warranting disciplinary suspension from the practice of law. Thus the facts in this case are of essential importance.
I—FACTS
Appellant represented a client, Earl Harmon, who was involved in a rear-end accident in East Lansing on September 7, 1965. Previously, without counsel, Harmon had consented to a judgment against him of $855.25 in favor of the City of East Lansing, owner of the truck that Harmon rear-ended. Appellant represented Harmon in a second suit, a personal injury action brought by a passen*590ger in the truck, Charles L. Malcomb, on June 26, 1967.
Appellant prepared an answer to the suit which he filed and mailed to Harmon; he took Harmon’s deposition on January 5, 1968. Appellant stated that he gave Harmon notice of deposition by letter after he was unable to reach Harmon by using the telephone number Harmon gave him. Just after the deposition was taken, appellant testified that he had a conversation with his client wherein Harmon agreed with appellant’s advice that liability had been "virtually admitted” and that the only issue remaining was damages. Appellant claims that this conversation constituted authorization to make "as good a settlement as he could on the damages”. It is a controverted question whether or not Harmon himself admitted or denied in his hearing-panel testimony that he was told by appellant that the damages were the only remaining issue, or whether he admitted or denied authorizing settlement.
A trial date was set in this action for February 16, 1971. On January 9, 1970, appellant consented to the entry of a summary judgment in favor, of plaintiff as to liability. On February 19, 1971, appellant consented to the entry of a consent judgment for damages in the sum of $30,654.35. No correspondence or conversations at all were had before entry of these judgments by appellant with Harmon after the January 5, 1968, conversation at Harmon’s deposition. Appellant stated that he attempted to phone his client before both the summary and consent judgments, but was unable to reach him; no written communications were attempted. Harmon testified that the first notification he had of these judgments was by the Secre*591tary of State when his operator’s license was revoked for failure to satisfy the consent judgment. During all this period, Harmon resided at the same address appellant wrote to in 1967. Appellant testified that Harmon’s home was about five miles from his office.
Appellant justifies his lack of contact with Harmon on the grounds that he was expressly authorized to make as good a settlement as possible and that the amount he consented to was $19,000 less than plaintiffs "confirmed damages”. Before the hearing panel, appellant admitted that he was aware that there was considerable doubt whether Harmon, a farm laborer, could pay a judgment of this magnitude.
A Board hearing panel found that appellant had violated Rule 14 (now Rule 15), §§ (1), (2), and (3) and an order was filed July 17, 1972, suspending appellant from the practice of law for one year. The Board affirmed the panel on October 18, 1972.
II—STANDARD FOR REVIEW
Appellant appealed to this Court under Rule 16.23 of the Michigan Supreme Court Rules for the State Bar Grievance Board from a final order of discipline. The initial issue to be resolved is the nature of our review on appeal of Board final orders. Traditionally, review of such orders has been in the nature of certiorari rather than de novo review. Attorney General v Lane, 259 Mich 283, 285-287; 243 NW 6 (1932); cert den 287 US 654; 77 L Ed 565; 53 S Ct 115 (1932); Attorney General v Nelson, 263 Mich 686, 700-701; 249 NW 439 (1933); Attorney General v Shaw, 289 Mich 468, 469; 286 NW 793 (1939); In re Estes, 355 Mich *592411, 424; 94 NW2d 916 (1959); cert den 361 US 829; 4 L Ed 2d 71; 80 S Ct 77 (1959).1
We have not had cause though to discuss the question of standard of review since the advent of new disciplinary rules and procedures effective March 1, 1970. It is significant that the new disciplinary procedures are, prior to final review by this Court, administrative and quasi-judicial in nature, rather than primarily judicial. Const 1963, art 6, § 28, provides in relevant part:
"Sec. 28. All final decisions, findings, rulings and orders of any administrative officer or agency existing under the constitution or by law, which are judicial or quasi-judicial and affect private rights or licenses, shall be subject to direct review by the courts as provided by law. This review shall include, as a minimum, the determination whether such final decisions, findings, rulings and orders are authorized by law; and, in cases in which a hearing is required, whether the same are supported by competent, material and substantial evidence on the whole record.”
Review in the nature of certiorari meets this constitutional requirement. It also serves to give real meaning to the powers and duties given the Board and hearing panels under Rule 16. We thus retain the standard for review established by case *593law prior to adoption of these new disciplinary rules. Thus we will not proceed to adjudicate this case de novo, but instead we will determine whether the Board’s findings have proper evidentiary support on the whole record.
Ill—EVIDENTIARY SUPPORT FOR FINDINGS
The hearing panel in this action made the following findings which were affirmed by the Board:
"CONCLUSIONS
"Upon careful consideration of the facts, the panel concludes as follows:
"1) That Respondent failed to fully and properly keep his client advised and informed of the proceedings in the cause pending against the Complainant and in which Respondent had undertaken to defend him.
"2) That Respondent failed to communicate with the Complainant Harmon, his client, and to obtain his consent to the entry of the Consent Judgment and for that matter consent to the entry of the partial summary judgment regarding liability.
"3) That he did not have authority either express or implied to consent to the entry of judgment for $30,654.35; that the decision as to whether a consent judgment ought to be agreed to is a decision which only a client can make after discussion with and advice by the attorney.
"4) That Respondent did in the premises violate Rule 14 [now Rule 15] (1) (2) (3).
"5) That the panel has considered carefully Respondent’s claim that he was left with the impression after the January 5, 1968, depositions, that he had authority to settle, but it is not convinced from the proofs presented that such authority was in fact given or that Respondent who had practiced law for many, many years could have been given that impression from the conversation which is alleged to have taken place at that time; that the panel has also carefully considered the lack of education, training, and experience of the *594Complainant having entered the 10th grade but not having completed same, and being a common laborer presently employed as a farm laborer which factor should have at the very least caused Respondent to exercise the utmost care in handling the affairs of the Complainant. The panel has also considered,carefully the failure of the Respondent to communicate with the Complainant Harmon except on the two occasions hereinabove referred to, his failure to give notice of trial, and of the entry of the judgment to the Respondent.”
This Court must now determine whether the whole record supports such findings. We conclude that it does.
Whether or not appellant was authorized to settle his client’s case is an issue which was a focal point of argument by both parties in their briefs to this Court and upon oral argument. (Conclusions 2, 3, 5.) It is quite clear that appellant stated in testimony before the hearing panel that he believed he had authority to settle, e.g.:
"At the time of the Deposition it was apparent that the liability was admitted. It was a question of damage and at that time, Mr. Harmon and I talked and I told him that it was a question of—now, it was simply a question of damages and he told me to hold the damage down because he didn’t think the man was hurt as bad as he claimed, but he authorized me to do the best I could in holding those damages down.
* * *
"I think I was authorized by Mr. Harmon to make as good a settlement as I could on the damages.
* * *
"I advised Mr. Harmon at the time of the pretrial conference that the summary judgment probably would enter. Now, he didn’t dispute their right to a summary judgment as far as liability. His question was on damages.
*595"No, I wouldn’t say let it go at that. I felt sincerely, I felt that after our conversation that he knew that there would be a judgment against him, and that he wanted me to make as good a settlement on the amount of that judgment as possible, and it was left that way.”
What is controverted is the simple question whether Harmon, on the record, admitted or denied authorization. Appellant relies primarily on the following colloquy before the hearing panel as supportive of his contention that Harmon admitted authorizing appellant to settle his case:
"Q. (Mr. Estes): Now, let’s bet [sic] back now to the conversation in the hallway. The suit by Mr. Malcomb was not for property damage, was it, Mr. Harmon?
"A. No, it was not.
”Q. And in our conversation down the hall, didn’t you authorize me to settle this suit with Mr. Harmon at as low a figure as I could?
"Chairman Piggott: With Mr. Malcomb?
”Q. (Mr. Estes): With Mr. Malcomb.
'A. I don’t know how you had that phrased there.
"Chairman Piggott: Would the reporter read the question back?
"(Thereupon, the question was read back by the reporter.)
"The Witness: I don’t recall saying that. No, I don’t.
"Q. (Mr. Estes): Well, do you recall telling me to settle the damage suit without going into court, did you not?
rA. No, I don’t recall that either.
”Q. You said you recalled authorizing me to settle the property damage suit and the property damage suit wasn’t involved in this Malcomb, was it?
“A. No.
”Q. Then if you authorized me to settle any damages that would be the damages in the Malcomb case, isn’t that right?
'A. Yes.”
*596Appellant incorrectly construes the import of this language. The only "admission” that Harmon made in the preceding testimony was the "admission” that if there were any authority given to settle, it was authority with respect to the Malcomb case. That is far different from admitting that such authorization was actually given. In fact, Harmon speciñcally denied giving any authorization in previous, and upon further, questioning by appellant, e.g.:
"Q. [Estes]: Now, as we went down the hall, didn’t you tell me that you thought Mr. Malcomb’s claim of damage was too much and that you wanted me to work out a settlement for as low a figure as possible?
”A. [Harmon]: fio, I don’t remember talking like that. * * *
"The Witness [Harmon]: All we talked about as we went down the hall is the guy passing away and about the City. That is all I recollect because we wasn’t in the hall that long to do all that talking. You didn’t ask me to come down to the office and talk. We was going down the hall and you mentioned that much, well, I think we might have this case won because the guy has passed away. Now, that is what you told me.
"Q. (Mr. Estes): All right. But didn’t in the course of the conversation, wasn’t it brought out that there was only the question of damages left?
"A. Yes. This is when you said we thought we had it won when he passed away.
”Q. But along with that, isn’t that the only question left that we had to dispose of, the question of damages?
”A. Not that—not of my knowledge.”
”Q. [Estes]: Do you recollect that you told me that you wanted me to settle that loss of wages item?
”A. [Harmon]: No, I don’t recollect that, no, saying that.
* * *
”Q. Did you—do you recall telling me that you *597wanted me to check into it and settle it as well as I could?
"A. I think I asked, asked you to check into the wages.
”Q. Now, in talking about the wages, we were talking about the claim of damage in the Malcomb suit against you, weren’t we?
”A. This is something I don’t recollect. It was an awful short hall and you wasn’t doing all that talking.
* * *
"Q. [Estes] And didn’t you tell me at that time that you would like the thing disposed of without a trial?
"A. [Harmon7 Not of my recollection, no.
"Q. You don’t recall telling me to settle it without a trial?
'A. No.
”Q. All you recall then apparently is that you wanted me to look into the question of loss of wages?
”A. Yes.”
We conclude that there was sufficient testimony and factual support on the record to enable the hearing panel and the Board to conclude, as they did, that appellant lacked authority to settle Harmon’s case. We will not substitute our judgment for that of the panel below which had an opportunity and a mandate not only to garner evidence of misconduct but to observe and assess the demeanor and credibility of the witnesses.
The second general finding of the hearing panel below, that appellant failed to inform Harmon of proceedings and judgments, (Conclusion 2) is less seriously controverted by appellant on the record. Appellant admitted at all stages of this proceeding that he did not communicate with his client from January 5, 1968, the date of the alleged "authorization to settle” until sometime subsequent to his consent to, and entry of, summary judgment as to liability on January 9, 1970, and consent judgment *598as to damages on February 19, 1971. Appellant’s only contention before the hearing panel was that he attempted to get in touch with Harmon by phone; but it is undisputed on that same record that appellant possessed Harmon’s correct address at minimum from the summons, that Harmon’s address remained unchanged during this period, that appellant had used that address in 1967 to mail to Harmon a copy of the answer to the complaint, and that Harmon’s house was only "about five miles” from appellant’s office. All of the preceding being a part of the record before the hearing panel and Board, we are compelled to conclude that there was sufficient evidence to support the findings made with respect to appellant’s failure to inform and communicate with his client.
IV—SUPPORT FOR DISCIPLINARY ACTION
Given the sufficiency of the evidence below to support the findings made, we are faced with the ultimate question whether such findings support disciplinary action.
The hearing panel based discipline on violation of Rule 15, §2 (1), (2) and (3) which reads as follows:
"Section 2. Grounds for Discipline in General.
"The following acts or omissions by a member of the bar of this State, individually or in concert with any other person or persons, shall constitute misconduct and shall be grounds for discipline whether or not the act or omission occurred in the course of an attorney-client relationship.
"(1) Conduct prejudicial to the proper administration of justice;
"(2) Conduct that exposes the legal profession or the courts to obloquy, contempt, censure or reproach;
*599"(3) Conduct that is contrary to justice, ethics, honesty or good morals.”
It is quite clear that the behavior of appellant as reflected in the factual findings of the Board hearing panel, falls within the grounds for discipline enumerated above.
An attorney’s negligence, inattention, or professional incompetence in handling clients’ affairs can constitute an ethical violation of standards imposed upon the Bar.2 Numerous. Michigan cases stand for the proposition that it is breach of an attorney’s ethical obligation to the Bar and to his or her client to settle a case without specific authority.3 Most recently, we held in Henderson v Great Atlantic & Pacific Tea Co, 374 Mich 142; 132 NW2d 75 (1965) that:
" '[A]n attorney at law has no power, by virtue of his general retainer, to compromise his client’s cause of action; but that precedent special authority or subsequent ratification is necessary to make such a compromise valid and binding on the client.’ ” 374 Mich 142, 147 (citing from 66 ALR 107).
Even more on point is the recent Court of Appeals decision in Hartman v Frontier City, Inc, 20 Mich App 274; 174 NW2d 48 (1969). The attorney in that case presumed authorization to settle from *600his client’s alleged permission "to do what you think is best.” Unanimously, the Court of Appeals noted:
"Certainly the granting of such a special authority requires more than the general statement that we are presented with here. Our review of the record convinces us that at least plaintiff did not have a 'full understanding of the provisions in the [proposed] settlement.’ ” 20 Mich App 274, 277.
It is clear from these cases that unauthorized settlement of a client’s cause (barring subsequent ratification) is, and has traditionally been, the sort of breach of an attorney’s ethical duty intended to be included within the disciplinary grounds outlined in Rule 15, § 2.
Similarly, the failure to disclose all relevant facts and information known by an attorney to his or her client has traditionally been regarded as breach of an attorney’s ethical obligation. Kukla v Perry, 361 Mich 311, 317; 105 NW2d 176 (1960); Storm v Eldridge, 336 Mich 424, 435; 58 NW2d 129 (1953).4 It is clear from this record that appellant not only failed to advise Harmon of the course and content of settlement negotiations, but even failed to advise him of the approaching trial date and the subsequent consent judgments. Certainly on these facts, it is quite clear that such conduct warrants appropriate disciplinary action.
V—CONCLUSION
We conclude that the hearing panel’s findings in *601this case are supported by competent evidence on the whole record. We further conclude that these findings fully support and warrant disciplinary action. However, this Court has been given the power under Rule 16.23(h) to make such order on appeal as we may deem appropriate. In view of that power and upon lengthy consideration of the facts on record and the equities in this particular case, we affirm the Board order of suspension, but reduce the period of suspension from 1 year to 60 days.
Order affirmed with the period of suspension reduced from 1 year to 60 days.
