Perhaps you should try some spelling variations:
"ley 1530 de 2012" » "ley 130 de 2012", "ley 100 de 2012", "ley 1480 de 2012", "ley 1500 de 2012", "ley 153 de 2012", "ley 1030 de 2012", "ley 1530 de 2016"
"ley 1930 de 2012" » "ley 1934 de 2012", "ley 130 de 2012", "ley 190 de 2012", "ley 1930 de 2016", "ley 1030 de 2012"
"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 137 de 2012"
"ley 1330 de 2015" » "ley 1340 de 2015", "ley 1333 de 2015", "ley 1335 de 2015"
"ley 103 de 2015" » "ley 1503 de 2015", "ley 1083 de 2015", "ley 100 de 2015"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (((((("ley 1530 de 2012") OR ("ley 1930 de 2012"))) OR ("ley 1537 de 2012"))) OR ((("ley 103 de 2015") OR ("ley 1330 de 2015"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"ley 1530 de 2012\") OR (\"ley 1930 de 2012\"))) or (\"ley 1537 de 2012\"))) or (((\"ley 103 de 2015\") or (\"ley 1330 de 2015\"))))~".
• Removing quotes may allow a broader search: (((((( ley 1530 de 2012 ) OR ( ley 1930 de 2012 ))) or ( ley 1537 de 2012 ))) or ((( ley 103 de 2015 ) or ( ley 1330 de 2015 ))))~.
• Adding a wildcard symbol may retrieve word variants: (((((("ley 1530 de 2012") OR ("ley 1930 de 2012"))) or ("ley 1537 de 2012"))) or ((("ley 103 de 2015") or ("ley 1330 de 2015"))))*.
