という理由でOn the grounds that
という理由で explicitly presents the preceding statement as the reason or grounds used for a decision, action, treatment, or outcome. It is especially useful when reasons are being named, recorded, quoted, or evaluated.
How it works
The part before という理由で is treated as a complete statement that can be called a reason or justification. The following clause tells you what was done or what happened on those grounds.
An institutional decision
大学は、設備点検が必要だという理由で、図書館を一日臨時休館にした。
The university closed the library for one day on the grounds that an equipment inspection was necessary.
AnalyzeThe university is explicitly presenting the need for an inspection as the grounds for its decision.
Reporting a reason without endorsing it
Because this expression labels or quotes the reason being used, it does not automatically mean that the speaker accepts that reason as true or fair. Surrounding language can show a neutral, doubtful, or critical attitude.
会社は「協調性に欠ける」という理由で彼を不採用にしたが、その評価には疑問が残る。
The company rejected him on the grounds that he lacked teamwork skills, but doubts remain about that assessment.
AnalyzeThe quoted wording identifies the company's stated grounds; the final clause makes clear that the writer does not simply accept the assessment.
Remember the linking form
With an affirmative nonpast noun or na-adjective, do not drop だ before という理由で.

The company rejected Tanaka's application on the grounds that he had no experience.
