British official and office language has many ways to describe a failure without naming a person.
The decision was taken: Someone decided, but the sentence does not say who.
There were failings: Things went wrong, and no one is named as the cause.
It fell between two stools: Two people or departments each thought it was the other’s job.
With hindsight: Nobody could have known at the time.
Lessons will be learned: The matter is closed, and nobody will be punished.
