Perhaps you should try some spelling variations:
"ley 1480 de 2012" » "ley 100 de 2012", "ley 1480 de 2015", "ley 1480 de 2016"
"ley 1437 del 2006" » "ley 1437 de 2006", "ley 1438 del 2006", "ley 137 del 2006"
"ley 1448 del 2006" » "ley 1448 de 2006", "ley 1098 del 2006", "ley 1341 del 2006", "ley 1438 del 2006", "ley 1443 del 2006"
"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 2012" » "ley 1341 de 2012", "ley 100 de 2012", "ley 142 de 2012", "ley 1340 de 2015", "ley 1340 de 2016"

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 1480 de 2012") OR ((((("ley 1437 del 2006") OR ("ley 1448 del 2006"))) OR ("ley 1944 del 2012"))))) OR ("ley 1340 de 2012"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"ley 1480 de 2012\") or (((((\"ley 1437 del 2006\") OR (\"ley 1448 del 2006\"))) or (\"ley 1944 del 2012\"))))) or (\"ley 1340 de 2012\"))~".
• Removing quotes may allow a broader search: (((( ley 1480 de 2012 ) or ((((( ley 1437 del 2006 ) OR ( ley 1448 del 2006 ))) or ( ley 1944 del 2012 ))))) or ( ley 1340 de 2012 ))~.
• Adding a wildcard symbol may retrieve word variants: (((("ley 1480 de 2012") or ((((("ley 1437 del 2006") OR ("ley 1448 del 2006"))) or ("ley 1944 del 2012"))))) or ("ley 1340 de 2012"))*.
