IIMC stands for 'inadvertant' instrument meteorlogical condition. So if it was 'inadvertant' he should not.

If the pilot made a decision to climb into the cloud because it was the best option at the time and was able to recover and make a safe landing I would say, be happy you have him.

Now if a pilot goes IFR intionsionally without a flight plan, the company or FAA may go after him.
