                                      ANNOTATIONS

Compiler's notes. — The 1915 Code compilers deleted from the end of former
subdivision 2 (now Paragraph A(2)) "and he shall appeal from the decisions of such
board to the territorial board of equalization whenever in his judgment the same should
be done, and a right of appeal in such cases is hereby given." The state board of
equalization, as provided for in the constitution, was in effect abolished by the
amendment to art. VIII, § 5, of the constitution adopted in 1914. The provisions
concerning appeals to the state board of equalization were repealed by Laws 1915, ch.
54, § 5. Provisions relating to county valuation protests boards and proceedings thereof
are compiled as 7-38-25 NMSA 1978 et seq.

(4).

Obligation of prosecutor. — The prosecutor is a public officer with duties quasi-
judicial in nature. The prosecutor’s obligation is not only to protect the public interest but
also the rights of the accused. In the performance of the prosecutor’s duties, the
prosecutor must not only be disinterested and impartial, but must also appear to be so.
State v. Hill, 1975-NMCA-093, 88 N.M. 216, 539 P.2d 236 (Ct. App. 1975).

Discretion to determine criminal charges. — The district attorney makes the
determination whether to file criminal charges and which charges to file. State v.
Session, 1978-NMCA-005, 91 N.M. 381, 574 P. 2d 600; State v. Estrada, 2001-NMCA-
034, 130 N.M. 358, 24 P.3d 793, cert. denied, 130 N.M. 459, 26 P.3d 103.

Familial relationship between defendant and district attorney. — Where defendant
claimed that the district attorney was a third cousin of the defendant and that in Navajo
culture, defendant and the district attorney had a clan relationship that made the district
attorney culturally the grandfather of defendant, and the district attorney swore in an
affidavit that although the district attorney was one-half Navajo, the district attorney was
unaware of any clan relationship with defendant, that the district attorney had never had
personal or direct contact with defendant until after the prosecution of defendant’s case
had begun, and that the district attorney had only recently discovered that the district
attorney’s grandmother was the sister of defendant’s great-grandfather, the trial court
did not abuse its discretion in determining that the familial relationship between the
district attorney and defendant was insufficient to create a personal bias that warranted
disqualification. State v. Juan, 2010-NMSC-041, 148 N.M. 747, 242 P.3d 314.

Disqualification of district attorney’s office. — Where defendant’s spouse wrote
letters to the disciplinary board and to the prosecutor’s supervisor and the prosecutor
had initiated a federal investigation into defendant’s spouse for stalking, the actions of
defendant’s spouse and the prosecutor did not create a disqualifying interest warranting
the recusal of the prosecutor and the district attorney’s office. State v. Trujillo, 2012-
NMCA-112, 289 P.3d 238, cert. granted, 2012-NMCERT-011.

Threats against a prosecutor. — A defendant does not create a disqualifying interest
and cannot choose his or her prosecutor for an underlying offense by the use of threats
against prosecutors. An entire district attorney’s office is not subject to disqualification
unless an individual prosecutor is disqualified and there is a danger that the
prosecutor’s bias or disqualifying interest will taint the remaining attorneys in the office
or give the appearance of impropriety to continued prosecution by other attorneys. State
v. Robinson, 2008-NMCA-036, 143 N.M. 646, 179 P.3d 1254, cert. denied, 2008-
NMCERT-002, 143 N.M. 666, 180 P.3d 673.

Historical law officer of the territory. — Prior to the adoption of the constitution the
district attorney was by statute the law officer of the territory, and was required to
represent the territory, within his district, in all cases, civil and criminal, and to give
advice, when requested, to territorial officials. State ex rel. Ward v. Romero, 1912-
NMSC-011, 17 N.M. 88, 125 P. 617.

Under the constitution, the district attorney is a part of the judicial system of the
state, and is a quasi-judicial officer. State ex rel. Ward v. Romero, 1912-NMSC-011, 17
N.M. 88, 125 P. 617.

District officer construed. — The words "district officer" used in N.M. Const., art. XX,
§ 3, refer to the district attorney and district judge, but the words were used to designate
the geographical limits within which such officer performed the duties of his office, and
did not refer to the nature and grade of the office. State ex rel. Ward v. Romero, 1912-
NMSC-011, 17 N.M. 88, 125 P. 617.

District attorney has no powers outside his district, nor does he have any
common-law powers. State ex rel. Attorney Gen. v. Reese, 1967-NMSC-172, 78 N.M.
241, 430 P.2d 399.

District attorney or attorney general to represent state in criminal proceedings. —
Although Subsection A does not require the district attorney to appear in a nonrecord
court such as the metropolitan court, 36-1-19 NMSA 1978 prohibits anyone other than
the attorney general's office and district attorney's office from representing the state in a
criminal proceeding, except on order of the court and with the consent of those offices.
State v. Baca, 1984-NMCA-096, 101 N.M. 716, 688 P.2d 34.

Institution of probation revocation proceedings. — Although the specific procedural
authority of 40A-29-20, 1953 Comp., had been repealed, the district attorney, as the
chief law officer of his district, had authority to institute probation revocation
proceedings. State v. Paul, 1971-NMCA-107, 82 N.M. 791, 487 P.2d 493.
Appearance on appeal in criminal cases. — District attorney has authority to take an
appeal, but it is the prerogative and duty of attorney general to brief the case and to
present it in supreme court, and a district attorney may appear on appeal in a criminal
case only by permission of the attorney general and in association with him. State v.
Aragon, 1950-NMSC-053, 55 N.M. 421, 234 P.2d 356, rev'd on other grounds, 1951-
NMSC-052, 55 N.M. 423, 234 P.2d 358.

Authority of district attorney to bind state agency. — When representing the state in
a prosecution for driving under the influence, a district attorney had the authority to bind
the motor vehicle division to the judgment and sentence which, pursuant to a plea
bargain, expressly provided that the conviction was to be treated as a first conviction.
Collyer v. State Taxation & Revenue Dep't Motor Vehicle Div., 1996-NMCA-029, 121
N.M. 477, 913 P.2d 665.

Office's immunity in defamation suit. — In a defamation suit arising out of a report
prepared by an assistant district attorney at the request of the district attorney, the trial
court's ruling of absolute immunity was based upon the concepts of judicial immunity,
because the office of district attorney is a quasi-judicial office, as well as executive
immunity, because that office has duties which cannot be properly classified as quasi-
judicial. Candelaria v. Robinson, 1980-NMCA-003, 93 N.M. 786, 606 P.2d 196.

No fee for representation of the county. — All services rendered to boards of county
commissioners by district attorneys are official duties. There are no legal services that
can be rendered by a district attorney for a board of county commissioners for which the
district attorney may exact extra compensation. Hanagan v. Board of Cnty. Comm’rs,
1958-NMSC-053, 64 N.M. 103, 325 P.2d 282.

If criminal complaint is filed by sheriff without consent of the district attorney, the
latter may at any time step in and take charge of the case and the prosecution on
behalf of the state, since he is the chief law enforcement officer and the state's
prosecutor in his district. 1939 Op. Att'y Gen. No. 39-3257.

District attorney may initiate a foreclosure action in the name of the county
treasurer interested in the particular assessment. 1958 Op. Att'y Gen. No. 58-77.

District attorneys are not required to defend sheriffs in civil suits. Their duties are
limited solely to representing the interests of the state in criminal and civil actions. 1959
Op. Att'y Gen. No. 59-98.

The district attorney is not obligated to represent a county sheriff in a civil suit. 1959 Op.
Att'y Gen. No. 59-47.

District attorney to "represent the county" and "advise county officials." These
terms are used in the generally accepted sense, namely, the district attorney is to serve
as attorney for the county in all matters when called upon to so act. The legislature
intended to make the district attorney the attorney for the counties of his district. 1956
Op. Att'y Gen. No. 56-6565.

District attorney to represent the county. — Whenever the county commissioners
request representation in any matter before them, it is the duty of the district attorney to
act for such county. 1956 Op. Att'y Gen. No. 56-6565.

Duty to advise state officers found in this section is limited to those matters
relating to and pending in the judicial district in which the district attorney is located - not
to matters of statewide application. 1961 Op. Att'y Gen. No. 61-61.

Duty to advise limited. — While a district attorney is to advise state officers within his
district when requested, this means "advise these officers on matters relating to the
judicial district in which he is located." 1961 Op. Att'y Gen. No. 61-61.
