________________________________________________

GRATTON, Chief Judge

Michael Shane Byington appeals from the district court’s order denying his petition for 

post-conviction relief following an evidentiary hearing. We reverse.

I.

FACTUAL AND PROCEDURAL BACKGROUND

Byington was convicted of aggravated assault following a jury trial. He received a 

unified five-year term with two years determinate, which was suspended in favor of a five-year 

term of probation. Byington filed a motion for a new trial based on newly discovered evidence, 

which was denied by the district court. Byington appealed the denial of that motion and this 

Court upheld the district court. See State v. Byington, Docket No. 35697 (Ct. App. Sept. 18, 

2009) (unpublished).

Byington then filed a petition for post-conviction relief alleging numerous claims of 

ineffective assistance of counsel. At the evidentiary hearing on his petition, Byington sought to 
2

introduce evidence concerning trial counsel’s failure to file a motion to suppress evidence--an 

issue not raised in his petition for post-conviction relief. The State objected on the basis that this 

claim was not pled and, therefore, waived. Byington was allowed to present evidence on the 

matter. After hearing argument, the district court requested additional briefing on this new 

claim. Byington filed both additional briefing on the issue and a supplemental1 petition for postconviction relief. The State, in turn, filed a memorandum in support of its objection. The district 

court then denied Byington’s petition and held that the new claim had been waived. Byington 

timely appealed. 

II.

DISCUSSION

The sole issue Byington raises on appeal is whether the district court erred by holding 

that his ineffective assistance of counsel claim was waived.

2

 As noted, Byington’s initial 

petition for post-conviction relief contained numerous claims of ineffective assistance, but did 

not contain an allegation that his trial counsel provided ineffective assistance for failing to file a 

motion to suppress evidence. The State argued that language in Stuart v. State, 118 Idaho 932, 

933-34, 801 P.3d 1283, 1284-85 (1990) suggested that a claim which should have been known at 

the time of filing of the initial petition is waived if not raised therein. The district court agreed 

with the State finding:

The Petitioner attempted to and in fact was allowed by the Court to 

introduce evidence of an alleged illegal custodial interrogation and subsequent 

search. These matters were not raised in the original Petition for Post Conviction

Relief. Therefore, the Court now rules that those claims were waived and will not be 

considered.

The district court’s use of the term “waived” is indicative of its reliance on Idaho Code 

§ 19-4908. That section provides: 

 

1 Under Idaho Rule of Civil Procedure 15(d) a supplemental pleading is proper when 

“transactions or occurrences or events [] have happened since the date of the pleading sought to 

be supplemented.” Here, the issue Byington wished to include did not occur after the original 

petition was filed, it was merely discovered by counsel after the initial petition was filed. 

Counsel should have filed a motion to amend the petition.

2 The other issues in Byington’s original petition for post-conviction relief are thus waived. 

See Monahan v. State, 145 Idaho 872, 874 n.1, 187 P.3d 1247, 1249 n.1 (Ct. App. 2008).
3

All grounds for relief available to an applicant under this act must be 

raised in his original, supplemental or amended application. Any ground finally 

adjudicated or not so raised, or knowingly, voluntarily and intelligently waived in 

the proceeding that resulted in the conviction or sentence or in any other 

proceeding the applicant has taken to secure relief may not be the basis for a 

subsequent application, unless the court finds a ground for relief asserted which 

for sufficient reason was not asserted or was inadequately raised in the original, 

supplemental, or amended application.

(emphasis added). 

The district court’s reliance on I.C. § 19-4908 was in error. The language in Stuart 

relates to a successive petition. If Byington had filed a successive petition, then the district court 

could have correctly rejected the petition on the basis that it was waived pursuant to I.C. § 19-

4908. Instead, Byington was attempting to add a claim to his initial petition. Therefore, the 

waiver provisions of I.C. § 19-4908 do not apply and his effort to amend his petition was instead 

governed by I.R.C.P. 15(a) and (b). The State argues on appeal that Byington failed to properly 

move to amend, the district court could properly deny any motion to amend, and the issue was 

not tried by consent of the parties. However, these assertions were not the basis of the district 

court’s refusal to consider the issue. Therefore, we do not address them on appeal. On remand, 

the district court should address whether Byington is allowed to amend his petition.

III.

CONCLUSION

The district court erred by holding that Byington’s ineffective assistance of counsel claim 

was waived because it was not included in his original petition. As such, we reverse the district 

court’s order denying Byington’s petition for post-conviction relief and the case is remanded for 

further proceedings.

3 We express no opinion as to whether or not the district court should allow Byington to 

amend his petition on remand.
