Ok this is not necessarily as you see.
the request is a past action but in this context it is obvious the person requested in the past that he be at the hearing NOW.
(Yesterday I requested it so that he would have time to be here today)
In 2) this sentecne expresses a wish. This type of wish follows the structure of conditional sentences type 2
If + past subjunctive + conditional
(If her boyfriend were here, she would be happy)
In this case we simply replace "if" by "I wish" continue with the past subjunctive, and omit the rest of the sentence.
