310 A.3d 1083
Md.2024Background
- The Maryland Public Service Commission ("Commission") approved the acquisition of Washington Gas by AltaGas Limited, imposing conditions including a requirement of at least $800,000/year in post-merger ratepayer savings for five years (Condition 44).
- The method for calculating these "merger-related savings" was disputed: whether it required actual cost cuts below pre-merger levels (as OPC claimed) or savings versus hypothetical costs had the merger not occurred (as Washington Gas/Commission claimed).
- Washington Gas later applied for a base rate increase; the Commission found its calculation of savings compliant with Condition 44.
- The Office of People’s Counsel (OPC) challenged the Commission’s interpretation, arguing both conditions 44 and 28 must be read together to require comparisons to 2016 cost levels.
- Judicial review (circuit court and Appellate Court of Maryland) affirmed the Commission’s decision, finding it was not arbitrary or capricious.
- The Supreme Court of Maryland granted certiorari to clarify the judicial standard for review and whether the Commission’s interpretation was arbitrary or capricious.
Issues
| Issue | Plaintiff’s Argument (OPC) | Defendant’s Argument (Commission/Washington Gas) | Held |
|---|---|---|---|
| Standard of Review for Commission's interpretation of its own order | Should not defer to the Commission; courts should adopt the parties' understanding at order's issuance | Highly deferential—apply “arbitrary or capricious” standard to Commission’s interpretation | Arbitrary/capricious standard applies |
| Proper interpretation of Condition 44 (merger savings) | Savings should be measured against actual pre-merger costs (2016, as required by Condition 28) | Savings are the difference from what costs would have been but for the merger, per Condition 44 only | Commission’s interpretation was not arbitrary or capricious |
| Link between Conditions 44 and 28 | They are "inextricably intertwined"; Condition 28’s reporting dictates measurement method for merger savings | Condition 44 is independent; Condition 28 is informational only, not binding for ratemaking | Commission’s separation of the two conditions was reasonable |
| Precedent/Consistency with past merger cases | Past Commission practice forbade hypothetical savings calculations as "too vague" | Commission distinguished this case and credited expert evidence proving direct ratepayer benefit | No inconsistency; Commission’s choice was reasonable |
