Analysis of Active Management - Reading 47 EOC Question 25

Hi all

Question 25 of the EOC questions asks for which proposed change would decrease the information ratio.

The answer is: Add maximum over- or underweight constraints on sector weightings.

Isn’t one of the golden rules of the Information Ratio that it is NOT affected by the aggressiveness of active weights?

I am very confused on why this is the correct answer. Any explanations would be much appreciated!
