==General Principles==
{{seealso|Role of the Crown}}

Prosecutorial discretion refers to the "discretion exercised by the Attorney-General in matters within his authority in relation to the prosecution of criminal offences”.<ref>
{{CanLIIRP|Anderson|g784t|2014 SCC 41 (CanLII)|[2014] 2 SCR 167}}{{perSCC-H|Moldaver J}}{{atL|g784t|44}}<br>
</ref>
It encompasses all "decisions regarding the nature and extent of the prosecution and the Attorney General's participation in it".<ref>
{{ibid1|Anderson}}{{atL|g784t|44}}<br>
{{CanLIIRPC|Krieger v Law Society of Alberta|51rs|2002 SCC 65 (CanLII)|[2002] 3 SCR 372}}{{perSCC|Iacobucci and Major JJ}}{{atL|51rs|47}}<br>
</ref> 
The prosecution is empowered with discretionary authority over many decisions that have limited ability to be reviewed. 

The discretion has its origins from the "Royal Prerogative of Justice and its enforcement in maintaining the King's Peace".<ref>
{{CanLIIRP|Smythe|1vkpf|1971 CanLII 30 (ON CA)|3 CCC (2d) 97}}{{perONCA|Wells CJHC}}{{atps|105 and 109}} aff'd at [http://canlii.ca/t/1twrk 1971 CanLII 831] (SCC){{perSCC-H|Fauteux CJ}}<br>
</ref>

The doctrine of prosecutorial discretion is not reviewable by courts except only on proof of abuse of process".<ref>
{{CanLIIRP|Nixon|flzgm|2011 SCC 34 (CanLII)|[2011] 2 SCR 566}}{{perSCC|Charron J}}{{atsL|flzgm|20|}}, {{atsL-np|flzgm|63| to 64}}<Br>
</ref>

Discretion must be exercised "in relation to a specific case" and not simply a blanket choice of what laws to enforce.<ref>
{{CanLIIRP|Catagas|g9w67|1977 CanLII 1636 (MB CA)|[1978] 38 CCC (2d) 296}}{{perMBCA|Freedman CJM}}{{atp|301}}<Br>
</ref>

Courts should be reluctant to interfere with prosecutorial discretion as they must respect the division of powers.<ref>
{{CanLIIRP|Power|1frvh|1994 CanLII 126 (SCC)|[1994] 1 SCR 601}}{{perSCC|L'Heureux‑Dubé J}}
("courts have been extremely reluctant to interfere with prosecutorial discretion is clear from the case law.  They have been so as a matter of principle based on the doctrine of separation of powers ...")<br>
see also {{CanLIIRP|Cook|1fr1f|1997 CanLII 392 (SCC)|[1997] 1 SCR 1113}}{{perSCC|L’Heureux‑Dubé J}}<br>
</ref>

Discretion is essential to keep the system from becoming "unworkably complex and rigid."<ref>
{{CanLIIRP|Beare|1jbbw|1988 CanLII 126 (SCC)|[1988] 2 SCR 387}}{{perSCC|La Forest J}}{{atp|410-411}}</ref>

Courts should not be reviewing the rationale for each and every decision of the Crown, it would be virtually impossible to have judge made rules to regulate the considerations involved. It would also create a conflict with the judge effectively regulating a prosecution.<ref>
{{supra1|Power}}{{atps|626-627}}<br>
</ref>

The court cannot direct the Crown on what offences they must prosecute.<ref>
{{supra1|Power}} (“A judge does not have the authority to tell prosecutors which crimes to prosecute...”.)<br>
</ref>

While the Attorney-General may enact policies that limit discretion, they are often considered undesirable.<ref>
e.g. {{CanLIIRP|K(M)|1npk4|1992 CanLII 2765 (MB CA)|74 CCC (3d) 108}}{{perMBCA| O'Sullivan JA}}{{Atp|110}} - commenting on "zero-tolerance" policy on prosecution</ref>

Core matters of prosecutorial discretion cannot be reviewed except for abuse of process. 

The conduct can be reviewed where the conduct of the Crown consituted a "marked and unacceptable departure from the reasonable standards expected of the prosecution"<ref> 
See {{CanLIIRP|974649 Ontario Inc|51xh|2001 SCC 81 (CanLII)|[2001] 3 SCR 575}}{{perSCC-H|McLachlin CJ}}<br>

==Calling Witnesses==
{{seealso|Inferences#Inference from Failing to Call Witnesses|Competence of Witnesses to Testify}}

The Crown does not need to call any witnesses it considers to be unnecessary.<ref>
{{CanLIIRPC|Lemay v The King|21v5b|1951 CanLII 27 (SCC)|[1952] 1 SCR 232}}{{fix}}{{atp|241}}<br> 
{{CanLIIRP|Jolivet|526w|2000 SCC 29 (CanLII)|[2000] 1 SCR 751}}{{perSCC-H|Binnie J}}{{atL|526w|14}}<br>
{{CanLIIRP|Ellis|fvkr6|2013 ONCA 9 (CanLII)|293 CCC (3d) 541}}{{perONCA|Watt JA}}{{atL|fvkr6|44}} ("As a matter of general principle, Crown counsel is under no obligation to call a witness whom the Crown considers is unnecessary to the Crown’s case...")
</ref> 
Likewise, the crown does not need to call unidentified witnesses or untrustworthy witnesses.<ref>
{{ibid1|Jolivet}}{{atL|526w|29}}</ref>

There is no obligation on the Crown to call any witnesses at all, short of it amounting to an abuse of process.<ref>
{{CanLIIRx|Rezaei|h36gx|2017 BCSC 611 (CanLII)}}{{perBCSC|Jenkins J}}<br>
{{CanLIIRP|Cook|1fr1f|1997 CanLII 392 (SCC)|[1997] SCJ No 2}}{{perSCC|L'Heureux-Dube J}}{{atL|1fr1f|56}}<br>
</ref>

The decision to call a witness on a related subject after the Crown had determined the witness is otherwise unreliable can be acceptable in some circumstances.<ref>
{{CanLIIRP|LL|gjqqr|2015 ABCA 222 (CanLII)|300 CCC (3d) 345}}{{TheCourtABCA}}<br>
</ref>

==Relationship with Police==
The Crown and police are to consult with each other but the "maintenance of a distinct line between these two functions is essential to the proper administration of justice."<ref>See Marshall Inquiry http://www.gov.ns.ca/just/marshall_inquiry/</ref>

The Crown can be liable for their part in giving advice to police during an investigation.<ref> 
see {{CanLIIRPC|Dix v Canada (Attorney General)|dwr|2002 ABQB 580 (CanLII)|96 CRR (2d) 1}}{{perABQB|Ritter J}}<br>

</ref>

While it is acceptable, the Crown should not try to be involved in interviews with parties prior to charges being laid.<ref>

==Evaluating Whether to Prosecute (Charge Screening)==

Most prosecution offices are guided by Crown Policy manuals requirements that there be a "reasonable prospect of conviction"<ref>Some provinces use difference standards such as "realistic prospects of conviction" (NS) or "substantial likelihood" (BC)</ref> and there is a "public interest" in the proceeding.<ref>
{{CanLIIRPC|Miazga v Kvello Estate|26g27|2009 SCC 51 (CanLII)|[2009] 3 SCR 339}}{{perSCC|Charron J}}{{atL|26g27|64}}
</ref>

One cannot evaluate the decisions of the Crown to proceed retroactively. The context of what was known at the time.<ref>
{{ibid1|Miazga v Kvello Estate}}{{atL|26g27|76}}<br>
</ref>

Considerations on the exercise of discretion must take into account the interest of the individual and the public interest.<ref>
{{CanLIIR-N|Harrigan and Graham| (1975), 33 CRNS 60}}{{perONCA|Henry J}}, stated{{Atp|69}} ("In exercising these powers, which vitally concern the right and liberty of the individual, he must take into account not only the interest of the individual but also what the public interest requires.")<Br>
{{CanLIIRP|Kenny|1p8vw|1991 CanLII 2738 (NL SC)|68 CCC (3d) 36}}{{perNLSC|Barry J}}
</ref>

Re-evaluation of proceedings can be based on aspects that come to light at trial:<ref> 
{{supra1|Miazga v Kvello Estate}}{{atL|26g27|76}}</ref>
* witnesses may not testify in accordance with their earlier statements; 
* weaknesses in the evidence may be revealed during cross-examination; 
* scientific evidence may be proved faulty; or 
* defence evidence may shed an entirely different light on the circumstances as they were known at the time process was initiated.

===Prospects of Conviction===
"Reasonable Prospects of Conviction" (RPC) is an objective test. 

RPC must be more than establishing a ''prima facie'' case against the accused.

RPC does not require that conviction is "likely".

The Crown is generally permitted consideration of the reliability of the complainant or witness. Determinations on the credibility of that person is often not appropriate and is done only exceptionally and on a limited basis.

{{reflist|2}}
=== Public Interest ===
The determination of public interest is primarily a function of the gravity of the offence and level of culpability of the offender.

While there are many elements that inform the gravity of the offence

The Crown considers the wishes of the alleged victim or complainant, including:
* the trauma caused by testifying and its effect on rehabilitation
* the social pressures upon the person from their involvement
* their willingness to cooperate and testify

There should also be careful consideration on whether it is possible to mitigate these issues through resources with the courts, victim services or police. For example, the use of testimonial aids may assist in the testimony. Real dangers to the person may be mitigated through police protections. Emotional trauma may be mitigated with victim services.

The Crown will usually not force a vulnerable victim to testify in a case where there is clear interest against doing so.

==Crown Election==
{{seealso|Crown Election}}
The decision to proceed either by summary conviction or by imdictment is an "essential component of the fair and efficient operation of the criminal justice system".<ref>
