Dr. Jagdeo is very educated and has vast experience in government that is unmatched by anyone in present day government. That's why many feared him, so the only thing they can do is to belittle him on things like when we addressed him as Dr. Whether Mr. Jagdeo earned a Ph.D., or he was conferred with one, it is legal to address him as Dr. Jagdeo. If anyone disagrees with me, present a challenge to the argument.
Indeed, it is legal for one to address him as Dr.
However, one will note that Bharrat Jagdeo does not use the title Dr. to his name.
Were Bharrat Jagdeo to use the title Dr. he will have to clearly state that it is an honorary title and referenced as "honoris causa".
In such case, the title will be noted as Dr. h.c , Dr(h.c) or Hon. Dr.
