What is the correct and most formal way to say "since it fulfills", "as it satisfies" or "meet" the conditions?

My university asks me to include this text on my thesis:

Prof. Dr. XXX, as director of the doctoral thesis YYY
by Mr. ZZZ in..., authorizes for submission since it has
the conditions necessary for its defence. 

But I think it doesn’t sound well.

Should I make any changes to improve it?

Prof. Dr. XXX, as director of the doctoral thesis YYY by
Mr. ZZZ in the..., authorizes for its submission since/as
it meets/fulfills/satisfies the conditions necessary/required
for its defence. 

I also don’t know if have to suppress that "for" nor if I should write "necessary conditions".
