Perhaps you should try some spelling variations:
"ley 1507 de 2012" » "ley 1607 de 2012", "ley 1503 de 2012", "ley 1508 de 2012", "ley 1500 de 2012", "ley 1507 de 2015"
"ley 1407 de 2012" » "ley 1437 de 2012", "ley 1607 de 2012", "ley 140 de 2012", "ley 1407 de 2015", "ley 1409 de 2012"
"ley 153 de 2012" » "ley 153 de 2015", "ley 1563 de 2012", "ley 1503 de 2012", "ley 1523 de 2012", "ley 2153 de 2012"
"ley 123 de 2016" » "ley 1273 de 2016", "ley 1523 de 2016", "ley 1123 de 2016", "ley 123 de 2015"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((((("ley 1507 de 2012") OR ("ley 1407 de 2012"))) or ("ley 153 de 2012"))) or ("ley 123 de 2016"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((((("ley 1507 de 2012") OR ("ley 1407 de 2012"))) OR ("ley 153 de 2012"))) OR ("ley 123 de 2016"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"ley 1507 de 2012\") OR (\"ley 1407 de 2012\"))) or (\"ley 153 de 2012\"))) or (\"ley 123 de 2016\"))*".
• Removing quotes may allow a broader search: (((((( ley 1507 de 2012 ) OR ( ley 1407 de 2012 ))) or ( ley 153 de 2012 ))) or ( ley 123 de 2016 ))*.
