# Separate labels in cases 2

Is there a cases package that lets me label my cases as I want? The cases and subcases environments of the cases package either labels tags with consecutive numbers or not at all. I would like some cases labeled and some not.

Does this answer your question: separate labels in cases. You can add \nonumber if you don't want an equation labelled. –  Peter Grill Nov 10 '11 at 19:52
You can also try the empheq package, as shown in this answer; the environment behaves like align, so accepts \label and \nonumber –  egreg Nov 10 '11 at 23:01

You can use \nonumber to suppress the tag:

\documentclass{article}
\usepackage{cases}

\begin{document}

\begin{numcases}{leftside}
case1 & explanation1 \nonumber\\
case2 & explanation2 \\
case3 & explanation3 \nonumber\\
case4 & explanation4
\end{numcases}

\end{document}
