Perhaps you should try some spelling variations:
"ley 15230 de 2016" » "ley 1523 de 2016", "ley 1530 de 2016", "ley 1563 de 2016", "ley 1330 de 2016"
"ley 15230 de 2015" » "ley 1523 de 2015", "ley 1530 de 2015", "ley 1563 de 2015", "ley 1330 de 2015"
"ley 1581 de 2012" » "ley 1341 de 2012", "ley 1480 de 2012"
"ley 153 de 2012" » "ley 1563 de 2012", "ley 1503 de 2012", "ley 1523 de 2012", "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 1581 de 2012") or ("ley 153 de 2012"))) or ((("ley 15230 de 2016") OR ("ley 15230 de 2015"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("ley 1581 de 2012") OR ("ley 153 de 2012"))) OR ((("ley 15230 de 2016") OR ("ley 15230 de 2015"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"ley 1581 de 2012\") or (\"ley 153 de 2012\"))) or (((\"ley 15230 de 2016\") OR (\"ley 15230 de 2015\"))))*".
• Removing quotes may allow a broader search: (((( ley 1581 de 2012 ) or ( ley 153 de 2012 ))) or ((( ley 15230 de 2016 ) OR ( ley 15230 de 2015 ))))*.
