Perhaps you should try some spelling variations:
"ley 1530 de 2012" » "ley 1537 de 2012", "ley 1930 de 2012", "ley 100 de 2012", "ley 1330 de 2012", "ley 1500 de 2012", "ley 153 de 2012"
"ley 1030 de 2012" » "ley 100 de 2012", "ley 1090 de 2012", "ley 1010 de 2012", "ley 1020 de 2012"
"ley 130 de 2016" » "ley 1340 de 2016", "ley 1310 de 2016", "ley 1306 de 2016"
"ley 130 de 2015" » "ley 1340 de 2015", "ley 1310 de 2015", "ley 1306 de 2015"
"ley 030 de 2016" » "ley 020 de 2016", "ley 038 de 2016", "ley 1090 de 2016"

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 1030 de 2012"))) OR ((((("ley 130 de 2016") OR ("ley 030 de 2016"))) OR ("ley 130 de 2015"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"ley 1530 de 2012\") or (\"ley 1030 de 2012\"))) or (((((\"ley 130 de 2016\") OR (\"ley 030 de 2016\"))) or (\"ley 130 de 2015\"))))~".
• Removing quotes may allow a broader search: (((( ley 1530 de 2012 ) or ( ley 1030 de 2012 ))) or ((((( ley 130 de 2016 ) OR ( ley 030 de 2016 ))) or ( ley 130 de 2015 ))))~.
• Adding a wildcard symbol may retrieve word variants: (((("ley 1530 de 2012") or ("ley 1030 de 2012"))) or ((((("ley 130 de 2016") OR ("ley 030 de 2016"))) or ("ley 130 de 2015"))))*.
