"ley 1563 de 2012" » "ley 1564 de 2012", "ley 1562 de 2012", "ley 1581 de 2012", "ley 1563 de 2015"
"ley 2153 de 2012" » "ley 2155 de 2012", "ley 2113 de 2012", "ley 2158 de 2012", "ley 2153 de 2015", "ley 2183 de 2012", "ley 02183 de 2012", "ley 21503 de 2012", "ley 21543 de 2012", "ley 2143 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 1537 de 2012") or ((((("ley 153 de 2012") OR ("ley 1563 de 2012"))) or ("ley 2153 de 2012"))))) or ("ley 1523 de 2016"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("ley 1537 de 2012") OR ((((("ley 153 de 2012") OR ("ley 1563 de 2012"))) OR ("ley 2153 de 2012"))))) OR ("ley 1523 de 2016"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"ley 1537 de 2012\") or (((((\"ley 153 de 2012\") OR (\"ley 1563 de 2012\"))) or (\"ley 2153 de 2012\"))))) or (\"ley 1523 de 2016\"))*".
• Removing quotes may allow a broader search: (((( ley 1537 de 2012 ) or ((((( ley 153 de 2012 ) OR ( ley 1563 de 2012 ))) or ( ley 2153 de 2012 ))))) or ( ley 1523 de 2016 ))*.
