Sub Articulo 136.1

You shouldn't touch \baselineskip in LaTeX anywhere.
\renewcommand{\baselinestretch}{1.1}
affects lines in paragraphs, including in a p entry of tabular.
\renewcommand{\arraystretch}{1.1} 
affects spacing of tabular rows: row spacing = \arraystretch*\baselinestretch
I imagine that you want widely spaced rows, but want single-spacing
within eact "p" column entry.
{\renewcommand{\baseleinestretch}{.6}
 \renewcommand{\arraystretch}{1.666}
