"ley 1310 de 2012" » "ley 1340 de 2012", "ley 1314 de 2012", "ley 1010 de 2012", "ley 1310 de 2016"
"ley 1355 de 2012" » "ley 1955 de 2012", "ley 115 de 2012", "ley 1341 de 2012", "ley 1355 de 2016"
"ley 1908 de 2012" » "ley 1508 de 2012", "ley 1968 de 2012", "ley 1008 de 2012", "ley 1908 de 2016", "ley 190 de 2012", "ley 1998 de 2012"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((((("ley 1310 de 2012") OR ("ley 1355 de 2012"))) OR ((("ley 1908 de 2012") OR ("ley 1978 de 2012"))))) OR ("ley 1930 de 2015"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"ley 1310 de 2012\") OR (\"ley 1355 de 2012\"))) OR (((\"ley 1908 de 2012\") OR (\"ley 1978 de 2012\"))))) OR (\"ley 1930 de 2015\"))".
• Removing quotes may allow a broader search: (((((( ley 1310 de 2012 ) OR ( ley 1355 de 2012 ))) OR ((( ley 1908 de 2012 ) OR ( ley 1978 de 2012 ))))) OR ( ley 1930 de 2015 )).
• Adding a wildcard symbol may retrieve word variants: (((((("ley 1310 de 2012") OR ("ley 1355 de 2012"))) OR ((("ley 1908 de 2012") OR ("ley 1978 de 2012"))))) OR ("ley 1930 de 2015"))*.
