I entered the following code in LaTeX:

\documentclass{article}
\begin{document}
\begin{enumerate}
\item[[$\Rightarrow$]]necessitiy
\item[[$\Leftarrow$]]sufficiency
\end{enumerate}
\end{document}

I got this:

The spacing is not exactly as I desired. I would like the ] to be as close to the arrow as the [ and I would like a little bit of space between the ] and the actual item.

  • I usually define some macros for the right implication and for the left one (only defined in the proof environment). \limplication, \rimplication or something like that. That way it's easy to change their behavior.

    Don't use a list; starting the paragraph with ($\Rightarrow$) is sufficient.

The solution is simple: protect the item label with braces:

\item[{[$\Leftarrow$]}]
