Perhaps you should try some spelling variations:
"ley 1563 de 2012" » "ley 1564 de 2012", "ley 1562 de 2012", "ley 1581 de 2012", "ley 1563 de 2015"
"ley 1523 de 2016" » "ley 1503 de 2016", "ley 1581 de 2016", "ley 142 de 2016", "ley 1523 de 2015"
"ley 030 de 2012" » "ley 020 de 2012", "ley 038 de 2012", "ley 130 de 2012", "ley 030 de 2015"
"ley 123 de 2016" » "ley 123 de 2015", "ley 1273 de 2016", "ley 1123 de 2016", "ley 1232 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 030 de 2012") or ("ley 1563 de 2012"))) or ((("ley 1523 de 2016") OR ("ley 123 de 2016"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("ley 030 de 2012") OR ("ley 1563 de 2012"))) OR ((("ley 1523 de 2016") OR ("ley 123 de 2016"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"ley 030 de 2012\") or (\"ley 1563 de 2012\"))) or (((\"ley 1523 de 2016\") OR (\"ley 123 de 2016\"))))*".
• Removing quotes may allow a broader search: (((( ley 030 de 2012 ) or ( ley 1563 de 2012 ))) or ((( ley 1523 de 2016 ) OR ( ley 123 de 2016 ))))*.
