Plummer v. United States
The Court ruled that a Navy doctor serving as a temporary "acting assistant surgeon" was entitled to be paid at the current rate for assistant surgeons as it existed while he served, not the lower rate that was in effect when Congress first created his temporary position in 1898.
The ruling meant the government owed him thousands of dollars in back pay, and it set the rule that pay tied by law to another rank rises and falls with that rank's actual pay over time, not a rate frozen at the moment the tie was created.
“a mere increase of the compensation of assistant surgeons without any change between the duties of those officers and the duties of acting assistant surgeons cannot justify the implication unless there was a clear manifestation of the purpose to do so”
Explaining why pay raises for regular surgeons should also apply to acting assistant surgeons doing the same work.
How it got here: The Court of Claims denied Plummer's claim for back pay, following its own earlier rulings in similar cases, and he appealed that judgment to the Supreme Court.
The Case in Depth
What happened
Plummer served as a temporary "acting assistant surgeon" in the Navy at the Key West Naval Station from 1903 to 1909. Congress had created these temporary positions in 1898 and tied their pay and rank to that of regular assistant surgeons. Over the following decade, Congress repeatedly raised the pay and rank of regular assistant surgeons, but the Navy kept paying Plummer at the original 1898 rate, reasoning that later pay raises applied only to permanent officers.
The question before the Court
When Congress raised the pay of Navy assistant surgeons over the years, did a temporary "acting" assistant surgeon get those same raises, or was he stuck with the old 1898 pay rate?
Why it matters
The decision meant a Navy doctor received over $4,000 in back pay he had been denied. More broadly, it clarified that when a federal statute ties one government position's pay to another position's pay, the tie tracks pay increases over time rather than freezing pay at the level that existed when the law was written — a principle relevant to many federal employees whose pay is set by cross-reference to another job's salary.
What changes now
The case is sent back to the Court of Claims with instructions to enter judgment for the claimant in the amount of $4,213.86, covering the pay difference, quarters commutation, and heat-and-light allowance he had been wrongly denied. The ruling resolved the legal question of how his pay should have been calculated, so no further merits proceedings were needed beyond entering the judgment.

How the Court got there
The legal reasoning, step by step
- The Court read the 1898 statute creating acting assistant surgeons as tying their pay to whatever pay was legally allowed to assistant surgeons, without freezing that standard to the rate in effect the moment the statute passed.
- Because the tie was meant to track an existing, living standard rather than an obsolete one, the Court reasoned that as Congress raised the pay and rank of regular assistant surgeons over time, that higher pay automatically became the benchmark for acting assistant surgeons performing the same duties.
- The Court found support for this reading in how the government itself had acted: the Navy's own recruiting circular for Plummer's position quoted the updated, higher pay scale rather than the original 1898 figures, and Plummer was commissioned at the assistant surgeon's current higher rank rather than the older, lower one.
- On the separate dispute over how to calculate the extra pay owed for years of service (called longevity pay), the Court looked to a rule Congress adopted in 1882 specifically to overrule an earlier Supreme Court decision, United States v. Tyler, which had required a more generous calculation method based on compounded prior pay increases.
- Because Congress had spent decades applying the 1882 method to equalize Army and Navy pay, the Court concluded that a later 1908 pay statute using similar wording must have intended the same, already-settled calculation method, not the method rejected in Tyler.
