Can you clarify what is meant by "abolished or he is, for reasons not connected with any misconduct on his part, required to vacate that post" from the text?
The phrase "abolished or he is, for reasons not connected with any misconduct on his part, required to vacate that post" refers to a situation where the person holding a civil post under the Union or a State may be asked to leave their position without being accused of misconduct. This could happen if the position itself is eliminated (abolished) or if there are other valid reasons for the person to lose their job, unrelated to any wrongdoing on their part.
