Move the Goalposts
“Move the goalposts” is a sports metaphor for unfairly changing the rules or target after a process has begun. Cambridge marks the idiom informal/disapproving; specialist archival research reports a figurative 1924 parliamentary example, far earlier than some later-popularity accounts.
It means to change rules, requirements, or targets during a process, usually in a way that makes success harder or unfair.

Further guidance
Contextual Examples
The team met the original requirement, but management moved the goalposts by adding a new approval condition afterward.
Updating next year’s target before the cycle begins is not automatically “moving the goalposts.”
Meaning
Cambridge defines the idiom as changing rules while someone is trying to do something in order to make it more difficult.
Meaning Boundary
It is about changing the standard during the process, not simply revising a plan before evaluation starts.
Origin boundary
The 1924 evidence is a reported attestation; it does not prove a unique coinage event.
Practical Use
Use it when rules, criteria, or targets are changed after a process has begun, especially in a way that makes success harder.
Reported 1924 Use
Word Histories reports a 1924 House of Commons debate account in which George Hardie said opponents wanted to “shift the goal posts.”
Sports Metaphor
The image comes from physically relocating goalposts so the target no longer stays where expected.
Tone Boundary
Informal and usually disapproving; in formal writing, name the changed criterion if precision matters.
