Perhaps you should try some spelling variations:
"ley 1503 de 2012" » "ley 1563 de 2012", "ley 1508 de 2012", "ley 1523 de 2012", "ley 1503 de 2015", "ley 1500 de 2012", "ley 103 de 2012"
"ley 1437 de 2012" » "ley 1480 de 2012", "ley 1448 de 2012", "ley 1437 de 2015"
"ley 1437 de 2016" » "ley 1480 de 2016", "ley 1448 de 2016", "ley 1437 de 2015"
"ley 1333 de 2012" » "ley 1341 de 2012", "ley 1438 de 2012", "ley 1340 de 2012", "ley 1333 de 2015"
"ley 153 de 2012" » "ley 1563 de 2012", "ley 1523 de 2012", "ley 1537 de 2012", "ley 153 de 2015", "ley 2153 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 153 de 2012") OR ("ley 1503 de 2012"))) or ((((("ley 1437 de 2012") or ("ley 1437 de 2016"))) or ("ley 1333 de 2012"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("ley 153 de 2012") OR ("ley 1503 de 2012"))) OR ((((("ley 1437 de 2012") OR ("ley 1437 de 2016"))) OR ("ley 1333 de 2012")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"ley 153 de 2012\") OR (\"ley 1503 de 2012\"))) or (((((\"ley 1437 de 2012\") or (\"ley 1437 de 2016\"))) or (\"ley 1333 de 2012\"))))".
• Removing quotes may allow a broader search: (((( ley 153 de 2012 ) OR ( ley 1503 de 2012 ))) or ((((( ley 1437 de 2012 ) or ( ley 1437 de 2016 ))) or ( ley 1333 de 2012 )))).
• Adding a wildcard symbol may retrieve word variants: (((("ley 153 de 2012") OR ("ley 1503 de 2012"))) or ((((("ley 1437 de 2012") or ("ley 1437 de 2016"))) or ("ley 1333 de 2012"))))*.
