Perhaps you should try some spelling variations:
"ley 2153 de 2012" » "ley 2155 de 2012", "ley 2113 de 2012", "ley 2158 de 2012", "ley 2183 de 2012", "ley 02183 de 2012", "ley 2153 de 2016"
"ley 1537 de 2012" » "ley 1437 de 2012", "ley 1581 de 2012", "ley 1438 de 2012", "ley 1537 de 2016", "ley 153 de 2012", "ley 1507 de 2012"
"ley 1537 de 2015" » "ley 1437 de 2015", "ley 1581 de 2015", "ley 1438 de 2015", "ley 153 de 2015", "ley 1507 de 2015"
"ley 137 de 2012" » "ley 137 de 2016", "ley 1437 de 2012", "ley 1379 de 2012", "ley 135 de 2012", "ley 1377 de 2012", "ley 137 del 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 2153 de 2012") or ((("ley 137 de 2012") or ((("ley 1537 de 2012") OR ("ley 1537 de 2015"))))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("ley 2153 de 2012") OR ((("ley 137 de 2012") OR ((("ley 1537 de 2012") OR ("ley 1537 de 2015"))))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"ley 2153 de 2012\") or (((\"ley 137 de 2012\") or (((\"ley 1537 de 2012\") OR (\"ley 1537 de 2015\"))))))*".
• Removing quotes may allow a broader search: (( ley 2153 de 2012 ) or ((( ley 137 de 2012 ) or ((( ley 1537 de 2012 ) OR ( ley 1537 de 2015 ))))))*.
