Seth Awuku, a candidate in legislative drafting at Athabasca University in Canada, has urged the police to preserve suspects' names, information, and rights.
Before the case is decided by a law court, he believes it is critical to guarantee that public opinion does not move against the accused.
Mr Awuku highlighted on JoyNews' The Law on Sunday that having the public on an accused's side might alter the outcome of their trial.
"I believe the police must do everything reasonable to guarantee that the accused's rights are not prejudiced or that things are brought to the public's attention that are likely to impair his right to a fair trial in our democracy," he added.
"More often than not, there are leaks with the aim of attempting to score, especially if the subject is a political case," Mr Awuku said, "and this has a tremendous impact on the rights of the accused and perhaps a fair trial." As a result, I believe the police and the media, in particular, must exercise caution in this regard.
There is a fair trial and the accused's rights are not violated."
The private lawyer was discussing the importance of including community punishment under Ghana's legislation.
Mr Awuku went on to say that just because someone is charged with a crime does not imply they are immediately guilty.
"Until a court of competent authority declares him guilty, he is deemed innocent," says the statement. "It's not enough for a person to be judged guilty on their own," he explained.
Regardless of the severity of the offense, the private legal practitioner asked the general public, the police, and the media to refrain from making biased comments and statements against the accused.
Mr Awuku said, "It is only after hearing all of the evidence, witnesses documentary or otherwise, that the court can properly conclude that this individual is guilty or innocent."
