A man who killed his neighbour during a row over dog fouling in Edinburgh is challenging his murder conviction.
Mustafa Elsherkisi, 49, was ordered to serve at least 15 years before he can ask to be freed, when he was found guilty of racially aggravated murder.
Elsherkisi, a Libyan national, stabbed Mohammed Idris Mirza, 47, in Stenhouse Gardens North on 26 May 2010. He was jailed in December 2010.
He has now lodged papers at the Court of Criminal Appeal in Edinburgh.
Elsherkisi's counsel, Margaret Scott QC, successfully argued for some of his grounds, which were refused at a sifting stage, to be reinstated ahead of a full hearing in the case.
Miss Scott said she wanted a ground of appeal alleging the trial misdirected the jury to be included.
Lord Justice Clerk, Lord Gill, sitting with Lord Osborne and Lord Wheatley, agreed to the move.
