present perfect or past perfect

Post by Zibigo »

Hi,
I'll much appreciate your help in choosing the proper grammatical form. Which sentence is correct:
1. How could it have happened that the data was disclosed?
2. How could it had happened that the data was disclosed?
But, maybe both are wrong and someone can suggest a proper one?
Thanks.

"Could had..." is impossible.

--> #1 is correct.
