What do you call someone who reviews, and approves or denies, an application?

The person who applies is called the applicant. What is the correct term to use for the one on the other side of an application? [such as a job application]

In my case, the applicant applies to be promoted as say, a super user. I want to know what is the correct way to name the one who approves or denies the application.

Solution 1:

In workflow software applications, this role is commonly called the approver.

Solution 2:

Depending on the type of application it is, you could use reviewer, or approval official. In a work setting, you might use the individual's official job title instead: hiring manager, e.g.

Solution 3:

In most job-application settings, the person "on the other side of an application" is a clerk, secretary, office worker, interviewer, owner, or employer. Particularly in small companies, the person who hands an applicant a form, tells them which boxes to complete, reads the form over, interviews the applicant, and accepts them or not, is one and the same, the company owner.
