Perhaps you should try some spelling variations:
"ley 1380 de 2012" » "ley 1480 de 2012", "ley 1383 de 2012", "ley 1310 de 2012", "ley 1330 de 2012", "ley 1380 de 2016"
"ley 1944 del 2012" » "ley 1943 del 2012", "ley 1934 del 2012", "ley 1341 del 2012", "ley 14 del 2012", "ley 1164 del 2012", "ley 1944 del 2015", "ley 1944 del 2018", "ley 1944 del 2016"
"ley 1340 de 2015" » "ley 1341 de 2015", "ley 100 de 2015", "ley 1480 de 2015"
"ley 143 de 2018" » "ley 1437 de 2018", "ley 1438 de 2018", "ley 1943 de 2018", "ley 143 de 2016", "ley 143 de 2017", "ley 143 de 2013", "ley 1443 de 2018"
"ley 143 de 2011" » "ley 1437 de 2011", "ley 1438 de 2011", "ley 1943 de 2011", "ley 143 de 2016", "ley 1443 de 2011"

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 1380 de 2012") OR ((((("ley 143 de 2018") OR ("ley 143 de 2011"))) OR ("ley 1944 del 2012"))))) OR ("ley 1340 de 2015"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"ley 1380 de 2012\") or (((((\"ley 143 de 2018\") OR (\"ley 143 de 2011\"))) or (\"ley 1944 del 2012\"))))) or (\"ley 1340 de 2015\"))~".
• Removing quotes may allow a broader search: (((( ley 1380 de 2012 ) or ((((( ley 143 de 2018 ) OR ( ley 143 de 2011 ))) or ( ley 1944 del 2012 ))))) or ( ley 1340 de 2015 ))~.
• Adding a wildcard symbol may retrieve word variants: (((("ley 1380 de 2012") or ((((("ley 143 de 2018") OR ("ley 143 de 2011"))) or ("ley 1944 del 2012"))))) or ("ley 1340 de 2015"))*.
