I might write it this way. 

foreach my $case ( @{$all_cases} ) {
    if (    $case_list
         && $case->{examiner} eq $case_list->[-1]->{examiner} ) {
        push @{ $case_list->[-1]->{casedata} }, $case;
    }
    else {
        push @{$case_list},
          {
            examiner => $case->{examiner},
            casedata => [$case]
          };
    }
}

That eliminates all the extra variables, and you're not looping over indices instead of elements, but it seems a little longer (even though it's really fewer statements).
