Perhaps you should try some spelling variations:
"ley 1030 de 2012" » "ley 1090 de 2012", "ley 1010 de 2012", "ley 1530 de 2012", "ley 1030 de 2015", "ley 1330 de 2012"
"ley 1503 de 2016" » "ley 1563 de 2016", "ley 1508 de 2016", "ley 1523 de 2016", "ley 1500 de 2016", "ley 103 de 2016", "ley 1503 de 2015"
"ley 130 de 2012" » "ley 1340 de 2012", "ley 1310 de 2012", "ley 1306 de 2012", "ley 130 de 2015", "ley 030 de 2012"
"ley 100 de 2012" » "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 130 de 2012") OR ("ley 1030 de 2012"))) OR ("ley 100 de 2012"))) OR ("ley 1503 de 2016"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"ley 130 de 2012\") OR (\"ley 1030 de 2012\"))) or (\"ley 100 de 2012\"))) or (\"ley 1503 de 2016\"))~".
• Removing quotes may allow a broader search: (((((( ley 130 de 2012 ) OR ( ley 1030 de 2012 ))) or ( ley 100 de 2012 ))) or ( ley 1503 de 2016 ))~.
• Adding a wildcard symbol may retrieve word variants: (((((("ley 130 de 2012") OR ("ley 1030 de 2012"))) or ("ley 100 de 2012"))) or ("ley 1503 de 2016"))*.
