Perhaps you should try some spelling variations:
"ley 1330 de 2012" » "ley 1340 de 2012", "ley 1335 de 2012", "ley 1310 de 2012"
"ley 1333 de 2012" » "ley 1341 de 2012", "ley 1437 de 2012", "ley 1438 de 2012"
"ley 1901 de 2012" » "ley 1801 de 2012", "ley 1971 de 2012", "ley 101 de 2012", "ley 191 de 2012", "ley 10901 de 2012", "ley 19081 de 2012", "ley 19201 de 2012"
"ley 1901 de 2016" » "ley 1801 de 2016", "ley 1971 de 2016", "ley 101 de 2016", "ley 191 de 2016", "ley 10901 de 2016", "ley 19081 de 2016", "ley 19201 de 2016"
"ley 190 de 2015" » "ley 1090 de 2015", "ley 1908 de 2015", "ley 1920 de 2015", "ley 100 de 2015", "ley 390 de 2015"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (((((("ley 1330 de 2012") OR ("ley 1333 de 2012"))) OR ((("ley 1901 de 2012") OR ("ley 1901 de 2016"))))) OR ("ley 190 de 2015"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"ley 1330 de 2012\") or (\"ley 1333 de 2012\"))) or (((\"ley 1901 de 2012\") OR (\"ley 1901 de 2016\"))))) or (\"ley 190 de 2015\"))~".
• Removing quotes may allow a broader search: (((((( ley 1330 de 2012 ) or ( ley 1333 de 2012 ))) or ((( ley 1901 de 2012 ) OR ( ley 1901 de 2016 ))))) or ( ley 190 de 2015 ))~.
• Adding a wildcard symbol may retrieve word variants: (((((("ley 1330 de 2012") or ("ley 1333 de 2012"))) or ((("ley 1901 de 2012") OR ("ley 1901 de 2016"))))) or ("ley 190 de 2015"))*.
