Executive Summary: Key Legal and Evidentiary Issues

• Judicial review of a Residential Tenancy Branch (RTB) decision concerning tenants’ claim for 12 months’ rent under s. 51(2) of the Residential Tenancy Act following a purchaser’s notice to end tenancy for landlord’s use.
• Core factual dispute over whether the purchaser’s son actually occupied the main house within a “reasonable period” and for the statutory minimum occupation period after the tenants vacated.
• Adequacy of the RTB arbitrator’s reasons was central, as the decision failed to explain why sworn evidence of occupation and corroborating witnesses was effectively rejected.
• Use and limits of adverse inferences and factual inferences from missing or imperfect evidence (e.g., lack of moving receipts, internet service details, and documentary corroboration) were scrutinized.
• Allegations of reasonable apprehension of bias against the arbitrator were advanced but dismissed as serious, unsubstantiated claims lacking a factual foundation.
• The court granted judicial review and remitted the matter to a different RTB presider, while declining to award costs to the substantially successful petitioner because of the unfounded bias allegations.

Factual background

The dispute arises from a residential property in North Vancouver consisting of a main house and a detached laneway house. The respondents were tenants in the main house under a residential tenancy. As part of his contract of purchase and sale, the petitioner purchaser required that the property be delivered with vacant possession of the main house. A notice to end tenancy was issued to the tenants on November 13, 2023, on the basis that the purchaser or a close family member intended to occupy the rental unit. The effective date for vacant possession was February 29, 2024, but the tenants vacated slightly earlier, on February 14, 2024. After possession, the purchaser began renovating the lower area of the main house in or about May 2024. By September 10, 2024, the main house had been rented out to new tenants. The crucial factual controversy centred on whether the purchaser’s adult son, Parham, actually moved into and occupied the main house in the period between the prior tenants’ departure and the arrival of the new tenants, and for how long.

Proceedings before the Residential Tenancy Branch

The RTB proceeding was initiated by the former tenants, who claimed statutory compensation equivalent to 12 months’ rent under s. 51(2) of the Residential Tenancy Act. Their position was that the landlord–purchaser had not fulfilled the stated purpose of the notice—occupation by the landlord or a close family member—because neither the purchaser nor his close family member had lived in the rental unit for the required statutory period after the tenancy ended. Section 51(2) requires the landlord or purchaser to pay 12 times the monthly rent unless it is established that the stated purpose for ending the tenancy was accomplished within a reasonable period and that the rental unit was used for that purpose for at least the prescribed minimum period (at least six months, in the circumstances of this case). The landlord–purchaser accepted that he bore the onus to show that his son moved into the main house within a reasonable time and remained there for at least six months. At the RTB hearing, held over two days, the petitioner called multiple witnesses, including himself, his son, a neighbour, two of the son’s friends, and a contractor. They also produced insurance and banking documents, utility and internet bills, and a photograph showing Parham and his friends inside the main house. Their evidence aimed to show that Parham moved into the main house on March 8, 2024, and lived there continuously until September 9, 2024.

The RTB decision and evidentiary treatment

The arbitrator ultimately found in favour of the tenants, concluding that the landlord had not accomplished the stated purpose of the notice or complied with the Act. In doing so, the arbitrator placed significant emphasis on perceived gaps or weaknesses in the landlord’s evidence. The decision noted the absence of moving-company receipts showing relocation into the property, characterized insurance and financial letters as not definitive proof that the property was Parham’s home address, and criticized the lack of documentary corroboration for the neighbour’s and friends’ testimony. The arbitrator also drew attention to the similarity of the friends’ evidence and the absence of corroborating records, such as additional photographs. One unusual element was the arbitrator’s skepticism that three young men would gather to study or work on a project without internet access at the main house, given that the internet plan was shown as starting mid-July, which the arbitrator viewed as undermining the credibility of their testimony about being in the main house earlier in June. The photograph of the three friends inside the main house, while not disputed, was not clearly integrated into the arbitrator’s explanation as corroboration of their description of being in that space.

Judicial review framework and standard of review

On judicial review in the Supreme Court of British Columbia, the court first addressed the applicable standard of review. Under the Residential Tenancy Act and the Administrative Tribunals Act, the RTB is treated as an expert tribunal with a strong privative clause. This attracted a standard of “patent unreasonableness” for findings of fact, law, and the exercise of discretion in matters within its exclusive jurisdiction. The court reviewed the established authorities describing patent unreasonableness: the decision must be openly, evidently, and clearly irrational or unsupported by any tenable line of analysis; it is a high threshold, and substantial deference is owed to the tribunal. The court also linked adequacy of reasons to this standard, emphasizing that while RTB reasons need not match the length or sophistication of court judgments, they must be sufficient to allow a reviewing court, the parties, and the public to understand how and why the decision was reached. In the RTB context, adequate reasons should identify the legal test, outline the key findings of fact and principal evidence relied upon, and apply those findings to the legal standard in a transparent way.

Insufficiency of reasons and treatment of adverse inferences

The court held that the arbitrator’s reasons fell short of the required threshold of intelligibility and justification. The statutory issue was narrow: whether the landlord established that Parham moved into the main house within a reasonable time and occupied it for at least the required six months. Yet the arbitrator did not clearly state whether she rejected the claim that Parham ever occupied the main house, or whether she accepted some occupation but found it too late or too short to satisfy the six-month requirement. Because this key factual determination was never clearly articulated, it was impossible to trace the logical path from the evidence to the conclusion that the landlord had not accomplished the stated purpose of the notice. The court noted that sworn evidence is generally presumed truthful, and where credibility is at the heart of a dispute, an adjudicator should disclose, even briefly, the basis for rejecting that evidence. In this case, the arbitrator did not expressly address the credibility of the landlord’s witnesses, nor did she explain why their accounts, apparently corroborated to some degree by a photograph and multiple witnesses, were set aside. The judge also examined the arbitrator’s reliance on adverse inferences and inferences from missing evidence. For example, the emphasis on the absence of a mover’s receipt was difficult to reconcile with the factual issues actually in dispute. It was undisputed that the family moved to the property; the real question was whether Parham moved into the main house as opposed to only the laneway house, and when. The court observed that a moving-company receipt might have shown only the property address and not distinguished between the two structures, rendering it of limited probative value on the key point. Similarly, skepticism about the young men working without internet, and the criticism that the friends’ testimony lacked documentary corroboration despite the existence of a photograph showing them in the main house, were poorly tied to the statutory questions of occupation and timing. The arbitrator’s decision, read as a whole, identified various pieces of evidence that “could have been better” but never clearly explained which facts she accepted or rejected and why, leaving the reviewing court unable to follow a rational chain of reasoning.

Rejection of the bias allegation

In addition to attacking the sufficiency of reasons, the petitioner alleged a reasonable apprehension of bias on the part of the arbitrator. He argued that the internal inconsistencies in the decision and the way evidence was characterized revealed a predisposition against the landlord. The amended petition set out how, in his view, the same evidence was treated inconsistently, sometimes dismissed as non-existent, sometimes as inadequate corroboration, and sometimes used only to support a narrower narrative of renovation rather than occupation. The court treated this allegation with caution and emphasized the seriousness of claiming bias. It reiterated that bias requires a factual foundation showing a state of mind that prevents impartial judgment; merely disliking the outcome or disagreeing with reasoning does not meet that threshold. On the record, there was no remark, conduct, or pattern that suggested a prejudged result or partiality. The court concluded that the arbitrator’s rejection of the tenant-landlord’s evidence—however inadequately justified in writing—did not, by itself, show bias. Accordingly, the allegation of reasonable apprehension of bias was dismissed as unfounded.

Remedy and disposition

Having found that the RTB decision did not provide sufficient reasons to permit meaningful review, the court granted the petition for judicial review. However, it emphasized that judicial review is not a fresh hearing on the merits and declined the landlord’s request that the court substitute its own decision on whether the statutory six-month occupation requirement had been met. Unlike in cases where only a question of statutory interpretation is at issue, here the central problem was the arbitrator’s failure to explain her factual findings and credibility assessments. The court therefore could not simply accept the landlord’s evidence as true and decide the merits; there could be legitimate, though unarticulated, credibility concerns that another trier of fact might properly explore. The appropriate remedy was to remit the matter to the RTB to be heard afresh by a different presider. The court then turned to costs. It held that the petitioner was substantially successful in obtaining the judicial review, and under the general rule costs would normally follow in his favour. Nevertheless, the judge considered the petitioner’s serious but unsubstantiated bias allegations against the arbitrator. Those accusations, brought without evidentiary support, were treated as a significant factor in exercising the court’s broad discretion on costs. As a result, the court declined to make any order for costs. In other words, the petitioner succeeded in having the RTB decision set aside and the matter remitted, but he received no monetary recovery by way of damages, compensation, or costs at this stage. The successful party on the judicial review is the petitioner (the landlord–purchaser), yet the total amount ordered in his favour in this decision is effectively zero, and any future compensation to either side will depend on the outcome of the rehearing before the RTB, which cannot be determined from this judgment.
