Fair Witness Professional Code

The Fair Witness Professional Code defines the witness as a disciplined observer rather than an investigator: the professional records what is seen and heard, but neither draws conclusions nor participates in the inquiry. Its demands become concrete when Ben Caxton hires James Oliver Cavendish to accompany him to Bethesda Medical Center and test whether the man there is truly Valentine Michael Smith. The code preserves the independence of the testimony, even as it limits what Caxton can learn from it.

Appointment and Protocol

Caxton brings Cavendish to Bethesda Medical Center alongside Mark Frisby, whose firm represents the Post syndicate. The choice of witness is deliberate: Cavendish’s standing before the Federation High Court and his reputation for total recall give his testimony unusual authority. His conspicuous white professional cloak marks him as a person set apart from ordinary participants, and the group observes the protocol that forbids discussing in his presence what he is expected to see or hear.

The code makes the witness’s role narrower than Caxton’s goal. Caxton hopes to establish the identity of the supposed Martian, but Cavendish is not there to help build a case or steer the examination. He can supply an account of the encounter, not a verdict about what it means. His professional neutrality is therefore not simply a personal manner; it is the condition that makes his report credible.

Observation Without Judgment

After leaving the hospital, Caxton asks Cavendish whether anything he observed convinced him that the patient was the Man from Mars. Cavendish carefully declines the premise: forming opinions is not his function. He sees and hears, and that is all. His answer preserves the distinction between evidence and inference at precisely the moment Caxton wants a conclusion.

That distinction frustrates Caxton because the hospital visit has not resolved the central uncertainty. He has seen a man of roughly the right age in a bed, but the other apparent supports for the identification are weak: Gil Berquist’s word carries little weight in Caxton’s eyes, and Caxton could not establish the supposed psychiatrist’s training. Caxton’s question presses Cavendish to convert observation into authentication; the code prevents him from doing so. Cavendish can describe the encounter, but he cannot certify the identity that Caxton is trying to prove.

The Calluses and the Limit of Assistance

Once his assignment is over, Cavendish removes the cloak and relaxes. He then mentions a detail that Caxton had not checked: the patient’s calluses. Cavendish explains that calluses can disclose something of a person’s life, and that someone raised on Mars, in roughly one-third of Earth’s gravity and without wearing Earth-style shoes, should have marks consistent with that environment. Recent time in space should have left traces as well. The observation offers Caxton a specific avenue for testing the patient’s identity, but it arrives only after the hospital visit has ended.

Caxton immediately wants to return and inspect the patient’s feet. Cavendish refuses to accompany him, explaining that suggesting the test would have been unethical while he was serving as a Fair Witness: he is not a participant, and even discussing the missed clue afterward risks professional discipline. He considers the disclosure itself an indiscretion and says Caxton will need another witness. The code thus governs not only what Cavendish may do during an examination, but also how far he may go in helping an investigator use his observations afterward.

Evidence, Ethics, and Uncertainty

The episode exposes a tension at the heart of the code. Cavendish’s restraint protects the credibility of what he reports, but it also leaves Caxton without an answer and delays a potentially useful physical check. The witness notices the kind of evidence that might matter, yet professional independence bars him from directing Caxton toward it during the assignment. Afterward, his disclosure is limited by the same ethic that made the observation trustworthy.

The code does not settle whether the patient is Valentine Michael Smith. Rather, it keeps that conclusion outside the witness’s authority. Cavendish’s report remains carefully bounded, while Caxton and Frisby must decide what to make of the incomplete evidence: Frisby considers the identification convincing on ordinary grounds, whereas Caxton remains doubtful. Their disagreement underscores the code’s central distinction—observation can be precise without making the observer the judge of its meaning.
