1.11.2 Non-finite clause as extraposed subject

Rule: An extraposed non-finite clause requires an active verb.

Examples of errors:

(1) It must be tried to find him.
(2) It was suggested to go ahead with the project.

It was

suggested planned intended

*to go ahead with the project that we/he, etc. should) go ahead with the project

Decide is an exception to this rule:

It was decided to go ahead with the project
