Opinion
The plaintiff, Keith Prioleau, appeals from the judgment of the trial court dismissing his appeal from a decision of the defendant commission on human rights and opportunities (commission). 1 The commission determined that there was no reasonable cause to believe that discriminatory or retaliatory practices had been committed and dismissed the plaintiffs complaint without a hearing. The plaintiff claims that the court improperly concluded thаt (1) the commission applied the proper legal standard to his claims and (2) the commission’s findings were supported by substantial evidence. Because we conclude that the court properly dismissed the plaintiffs appeal, we affirm the judgment of the trial court.
*778 On October 23,2003, the plaintiff was laid off from his position as a senior computer scientist and information security specialist at Computer Sciences Corporation (company). Priоr to his layoff, the plaintiff worked in the company’s global infrastructure security services department and was assigned to its account with United Technologies Corporation (United). On March 30, 2004, the plaintiff filed a complaint with the commission in which he claimed that he had been laid off by the company because of his race and color and in retaliation for his participation in protected activity; specifically, he had opposed the discriminatory conduct of his former employer, which, at the time he was laid off, was a client of the company. 2 On May 24, 2004, the company filed its answer in which it asserted nondiscriminatory bases for the plaintiffs layoff. These bases included an economic downturn that necessitated a large and ongoing reduction in force, the fact that the plaintiff’s position had no direct impact on service level agreements 3 between the company and United and issues involving the reliability of the plaintiff. The plaintiff countered these assertions in a July 27, 2004 rebuttal, claiming that the company’s contentions were merely a pretext for its discriminatory and retaliatory *779 practices and offered evidence to support his allegations.
On September 7,2004, the commission, after conducting a merit assessment review pursuant to General Statutes § 46a-83 (b) 4 and concluding that issues of credibility existed that could not be resolved through that procedure, set the plaintiffs complaint for a full investigаtion and assigned a commission investigator. The purpose of the full investigation of the complaint was to ascertain whether there was reasonable cause to believe that discriminatory or retaliatory practices had been committed as alleged in the plaintiffs complaint. See General Statutes § 46a-83 (c). 5 If the commissioner or investigator found that there was “reasonable cause” to believe that discriminatory or retаliatory acts had been committed and if the complaint was not settled through the procedures outlined in § 46a-83, the *780 plaintiff would be entitled to a hearing on the matter. See General Statutes § 46a-84.
On October 7, 2005, the commission investigator, Theresa Plato, conducted a formal fact-finding proceeding on the record in which sworn witnesses gave testimony regarding the complaint. At the proceeding, Plato heard from the plaintiff, his former supervisor at thе company, Douglas Iosbaker, as well as another company employee, Ginger Roberts. The plaintiff, acting pro se, and the company’s attorney were allowed through the investigator to ask questions of the witnesses. After that fact-finding proceeding, both the plaintiff and the company submitted additional evidence.
On February 23, 2006, the commission issued a draft summary finding of no reasonable cause. James M. Flynn, a regional manager with the commission, forwarded a copy of the draft summary finding to the plaintiff. Accompanying the draft summary finding was a letter from Flynn in which he stated that the plaintiff had fifteen days to comment on the draft summary finding. No comments were received by the commission, and, on March 13, 2006, it made its finding of no reasonable cause final. On March 14, 2006, the plaintiff filed a request for reconsideration of the finding of no reasonable cause. On May 15, 2006, the commission issued a written decision denying the plaintiffs request for reconsideration. The plaintiff appealed from the commission’s decision to the Superior Court. On July 31, 2008, by memorandum of decision, the court dismissed the plaintiffs appeal. This appeal followed.
“We first note the limited scope of review to be exercised by the trial court in reviewing a [commission] determination that there is no reasonable cause to believe that a discriminatory practice has been committed. Judicial review of an administrative agency decision requires a court to determine whether there is *781 substantial evidence in the administrative record to support the agency’s findings of basic fact and whether the conclusions drawn from those facts are reasonable. . . . This so-called substantial evidence rule is similar to the sufficiency of the evidence standard applied in judicial review of jury verdicts, and evidence is sufficient to sustain an agency finding if it affords a substantial basis of fact from which the fact in issue can be reasonably inferred. . . . [I]t imposes an important limitation on the power of the courts to overturn a decision of an administrative agency . . . and to provide a more restrictive standard of review than standards embodying review of weight of the evidence or clearly erroneous action. . . . The United States Supreme Court, in defining substantial evidence in the directed verdict formulation, has said that it is something less than the weight of the evidence, and the possibility of drawing two inconsistent conclusions from the evidence does not prevent an administrative agency’s finding from being supported by substantial evidence. . . . This substantial evidence rule is embodied in General Statutes § 4-183 (j) (5) and (6).
“The substantial evidence standard is satisfied if the record provides a substantial basis of fact from which the fact in issue can be reasonably inferred. . . . The issue before the trial сourt, therefore, was whether there was a substantial basis in the record to support the commission’s finding of no reasonable cause for either the discrimination or retaliation allegation. As [our Supreme Court] noted previously, the term reasonable cause as used in ... § 46a-83 is synonymous with the term probable cause. . . . Probable cause is a bona fide belief in the existence of facts essential under the law for the action and such as would warrant a [person] of ordinary caution, prudence and judgment, under the circumstances, in entertaining it. . . . Probable cause is a flexible common sense standard. ... It deals with
*782
probabilities, and the application of the factual and practical considerations of everyday life on which reasonable and prudent [people] act. ... In order to determine whether there was substantial evidence in the record to support the cоmmission’s determination, the commission must have conducted a complete and thorough investigation.” (Internal quotation marks omitted.)

The plaintiff first claims that the court improperly concluded that the commission applied the proper legal standard to his claims of racial discrimination and retaliation.

The plaintiff next claims that the court improperly concluded that the commission’s findings were supported by substantial evidence. The plaintiff makes two arguments in this regard: because the commission’s finding of no reasonable cause was made on the basis of an inadequate investigation, it was not supported by substantial evidence; and even if the investigation was *785 adequate, the finding of no reasonable cause is not supported by substantial evidence. We disagree.

Inadequate Investigation

Substantial Evidence
The plaintiffs last claim, that the court improperly concluded that the commission’s finding was supported by substantial evidence, essentially is made on the ground that the credibility assessmеnt of the evidence and witnesses made by the investigator and adopted by the commission was in error. In essence, the plaintiff argues that the evidence he submitted was substantial evidence supporting a finding of reasonable cause and that the evidence submitted by the company was not substantial. 9 We do not agree.
“In determining whether an administrative finding is supported by substantial evidence, the reviewing court
*788
must defer to the agency’s assessment of the credibility of witnesses. . . . The rеviewing court must take into account contradictory evidence in the record . . . but the possibility of drawing two inconsistent conclusions from the evidence does not prevent an administrative agency’s finding from being supported by substantial evidence . . . .” (Citations omitted; internal quotation marks omitted.)

v.
Dept. of Health Services,
The judgment is affirmed.
In this opinion the other judges concurred.
Notes
R. Hamisi Ingram, a former executive director of the commission, also was named as a defendant but is not a party to this appeal.
The claimed protected activity was the plaintiffs participation in an action brought in federal District Court against Sikorsky Aircraft Corporation alleging racial discrimination in hiring and compensation and a racially hostile work environment. Judgment was entered against the plaintiff in that matter on September 24, 2003.
The record reveals that service level agreements are contractual agreements that provide incentives to the company to meet predetermined monthly service levels for its clients. Douglas Iosbaker, the plaintiff’s supervisor, testified at the October 7, 2005 fact-finding proceeding that “there are specific service levels within that contract [with United] that [United] measures [the company’s] performаnce by or on [that could result] in financial impact to [the company] if that service level was not met.” Also, in its May 24, 2004 answer to the plaintiffs complaint, the company asserted that it could suffer substantial financial penalty if the service level agreements were not met in any given month.
General Statutes § 46a-83 (b) provides in relevant part: “Within ninety days of the filing of the respondent’s answer to the complaint, the executive director or the exeсutive director’s designee shall review the file. The review shall include the complaint, the respondent’s answer and the responses to the commission’s requests for information, if any, and the complainant’s comments, if any, to the respondent’s answer and information responses. If the executive director or the executive director’s designee determines that the complaint fails to state a claim for relief or is frivolous on its face, that thе respondent is exempt from the provisions of this chapter or that there is no reasonable possibility that investigating the complaint will result in a finding of reasonable cause, the complaint shall be dismissed. . . .”
General Statutes § 46a-83 (c) provides in relevant part: “The executive director of the commission or his designee shall determine the most appropriate method for processing any complaint pending after review in accordance with subsection (b) of this section. The commission may conduct mandatory mediation sessions, expedited or extended fact-finding conferences or complete investigations or any combination thereof during the investigatory process for the purpose of finding facts, promoting the voluntary resolution of complaints or determining if there is reasonable cause for believing that a discriminatory practice has been or is being committed as alleged in the complaint. As used in this section and section 46a-84, reasonable cause means a bona fide belief that the material issues of fact are such that a person of ordinary caution, prudence and judgment could believe the facts alleged in the complaint. . . .”
Our Supreme Court “had occasion to explain the operation of this framework in
Craine
v.
Trinity College,
As noted previously, the company defended its layoff of the plaintiff by asserting, inter alia, that his position was selected for a reduction in force because his duties did not directly affect the company’s service level agreements with its clients. See footnote 3. The plaintiff now asserts on appeal that the commission inadequately investigated those agreements. Our review of the plaintiffs appellate briefs reveals that this claim first was asserted during oral argument before this court. We generally do not consider claims raised for the first time at oral argument. See
Blumenthal
v.
Kimber Mfg., Inc.,
We note that the record reveals that the plaintiff did not submit any comments to the commission in response to its draft finding of no reasonable cause.
The plaintiff bolsters this argument by asserting that the commission and the court were bound to draw all reasonable inferences from the evidence submitted in his favor. This issue was disposed of in part I and will not be revisited here.
Also, for the first time in his reply brief, the plaintiff claims that the substantial evidence test is not met because the finding of no reasonable cause was made prior to two subsequent complaints of discrimination he made to the commission involving the company in which the commission did find reasonable cause to believe that discriminatory practices had taken place. He argues that thеse subsequent complaints were made on the basis of the same set of circumstances as the complaint relevant to this appeal and, therefore, we should consider them in our resolution of his appeal. First, we note that “[i]t is a well established principle that arguments cannot be raised for the first time in a reply brief.” (Internal quotation marks omitted.)
