"ley 1437 de 2012" » "ley 1480 de 2012", "ley 1448 de 2012", "ley 1437 de 2015", "ley 1437 de 2016"

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((((("ley 130 de 2012") OR ("ley 1306 de 2012"))) or ((("ley 1437 de 2012") or ("ley 1341 de 2012"))))) or ("ley 1310 de 2012"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((((("ley 130 de 2012") OR ("ley 1306 de 2012"))) OR ((("ley 1437 de 2012") OR ("ley 1341 de 2012"))))) OR ("ley 1310 de 2012")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"ley 130 de 2012\") OR (\"ley 1306 de 2012\"))) or (((\"ley 1437 de 2012\") or (\"ley 1341 de 2012\"))))) or (\"ley 1310 de 2012\"))".
• Removing quotes may allow a broader search: (((((( ley 130 de 2012 ) OR ( ley 1306 de 2012 ))) or ((( ley 1437 de 2012 ) or ( ley 1341 de 2012 ))))) or ( ley 1310 de 2012 )).
• Adding a wildcard symbol may retrieve word variants: (((((("ley 130 de 2012") OR ("ley 1306 de 2012"))) or ((("ley 1437 de 2012") or ("ley 1341 de 2012"))))) or ("ley 1310 de 2012"))*.
