Perhaps you should try some spelling variations:
"ley 15230 de 2015" » "ley 1523 de 2015", "ley 1620 de 2015", "ley 1503 de 2015", "ley 1330 de 2015"
"ley 1530 de 2012" » "ley 1537 de 2012", "ley 130 de 2012", "ley 1930 de 2012", "ley 1330 de 2012", "ley 153 de 2012", "ley 1030 de 2012"
"ley 1563 de 2012" » "ley 1564 de 2012", "ley 1581 de 2012", "ley 1761 de 2012"
"ley 1562 de 2012" » "ley 1564 de 2012", "ley 1581 de 2012", "ley 142 de 2012"
"ley 1500 de 2016" » "ley 100 de 2016", "ley 1503 de 2016", "ley 1508 de 2016"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("ley 1530 de 2012") or ((("ley 1563 de 2012") OR ("ley 1562 de 2012"))))) or ((("ley 1500 de 2016") or ("ley 15230 de 2015"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("ley 1530 de 2012") OR ((("ley 1563 de 2012") OR ("ley 1562 de 2012"))))) OR ((("ley 1500 de 2016") OR ("ley 15230 de 2015"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"ley 1530 de 2012\") or (((\"ley 1563 de 2012\") OR (\"ley 1562 de 2012\"))))) or (((\"ley 1500 de 2016\") or (\"ley 15230 de 2015\"))))*".
• Removing quotes may allow a broader search: (((( ley 1530 de 2012 ) or ((( ley 1563 de 2012 ) OR ( ley 1562 de 2012 ))))) or ((( ley 1500 de 2016 ) or ( ley 15230 de 2015 ))))*.
