Evgeny Ryzhov (“Ryzhov”) appeals an order dismissing his petition for 

writ of mandamus. We have jurisdiction.1 Fla. R. App. P. 9.030(b)(1)(A). 

Because the trial court correctly recognized it lacked the authority to order

the named law enforcement agencies to investigate and prosecute certain 

individuals, we affirm. 

Ryzhov petitioned the trial court to compel Manuel A. Morales, the 

Chief of the Miami Police Department, and several other law enforcement 

agencies2 to investigate and prosecute various crimes he alleges were 

committed against him. The trial court dismissed the petition as facially 

insufficient, finding that requiring a law enforcement agency to conduct a

criminal investigation interferes with the exercise of that law enforcement 

agency’s discretion. This appeal followed.

On appeal, Ryzhov argues the trial court erred in dismissing his petition

for writ of mandamus because he has alleged a clear legal right to 

performance, an indisputable legal duty and no adequate remedy at law. 

See Fla. Agency for Health Care Admin. v. Zuckerman Spaeder, LLP, 221 

1 “A trial court’s dismissal of a petition for a writ of mandamus is reviewed by 

direct appeal.” Thomas v. Fla. Parole Comm’n, 963 So. 2d 777, 778 (Fla. 

1st DCA 2007). 2 The petition also named Edward Santiago in his capacity as the Police 

Chief of the Sunny Isles Beach Police Department and Mark Glass in his 

capacity as the Commissioner of the Florida Department of Law 

Enforcement.

So. 3d 1260, 1263 (Fla. 1st DCA 2017) (“In order to be entitled to a writ of 

mandamus, the petitioner must have a clear legal right to the requested 

relief, the respondent must have an indisputable legal duty to perform the 

requested action, and the petitioner must have no other adequate remedy 

available.” (quoting Putnam Cnty. Env’t Council v. Johns River Water Mgmt. 

Dist., 168 So. 3d 296, 298 (Fla. 1st DCA 2015))).

We disagree. In Florida, “[t]here has never been a common law duty 

of care owed to an individual with respect to the discretionary judgmental 

power granted a police officer to make an arrest and to enforce the law.” 

Everton v. Willard, 468 So. 2d 936, 938 (Fla. 1985); see also Schmitt v. State, 

590 So. 2d 404, 409 (Fla. 1991) (recognizing that police forces should be 

given discretion to investigate the probability that a crime has occurred). To 

require a law enforcement agency to investigate and invoke the criminal 

process violates the separation of powers, “one of the structural pillars upon 

which American freedoms rest.” Detournay v. City of Coral Gables, 127 So. 

3d 869, 873 (Fla. 3d DCA 2013). To require a state attorney to charge and 

prosecute likewise violates this constitutional doctrine. See Trianon Park 

Condo. Ass’n, Inc. v. City of Hialeah, 468 So. 2d 912, 922 (Fla. 1985) (stating 

that a police officer’s discretionary power to enforce a criminal statute is no 

different from the discretionary power exercised by a prosecutor in deciding 
4

whether to prosecute); Valdes v. State, 728 So. 2d 736, 738-39 (Fla. 1999) 

(“This Court has long held that as the prosecuting officer, the state attorney 

has ‘complete discretion’ in the decision to charge and prosecute and the 

judiciary cannot interfere with this ‘discretionary executive function.’” (internal 

citation omitted) (quoting State v. Bloom, 497 So. 2d 2, 3 (Fla. 1986))). 

Thus, there is no clear legal right to the requested relief and the 

respondents here do not have an indisputable legal duty to perform the 

specific requested action. Moreover, because the trial court has no authority 

to interfere with a law enforcement agency’s discretion to pursue an 

investigation or a state attorney’s discretion in deciding whether and how to 

prosecute, we find the trial court did not err in dismissing Ryzhov’s petition. 

Affirmed.
