Perhaps you should try some spelling variations:
"ley 1030 de 2012" » "ley 1090 de 2012", "ley 1010 de 2012", "ley 130 de 2012", "ley 1330 de 2012", "ley 1030 de 2015"
"ley 1306 de 2012" » "ley 1346 de 2012", "ley 130 de 2012", "ley 1336 de 2012", "ley 1306 de 2015", "ley 1302 de 2012", "ley 106 de 2012"
"ley 1530 de 2016" » "ley 1537 de 2016", "ley 130 de 2016", "ley 1930 de 2016", "ley 15630 de 2016", "ley 15030 de 2016", "ley 15230 de 2016", "ley 1330 de 2016", "ley 1500 de 2016", "ley 1530 de 2015"
"ley 100 de 2012" » "ley 100 de 2015"
"ley 153 de 2012" » "ley 153 de 2015", "ley 1563 de 2012", "ley 1503 de 2012", "ley 1523 de 2012", "ley 2153 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 1030 de 2012") OR ("ley 100 de 2012"))) or ("ley 1306 de 2012"))) or ("ley 153 de 2012"))) or ("ley 1530 de 2016"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((((((("ley 1030 de 2012") OR ("ley 100 de 2012"))) OR ("ley 1306 de 2012"))) OR ("ley 153 de 2012"))) OR ("ley 1530 de 2016"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((((\"ley 1030 de 2012\") OR (\"ley 100 de 2012\"))) or (\"ley 1306 de 2012\"))) or (\"ley 153 de 2012\"))) or (\"ley 1530 de 2016\"))*".
• Removing quotes may allow a broader search: (((((((( ley 1030 de 2012 ) OR ( ley 100 de 2012 ))) or ( ley 1306 de 2012 ))) or ( ley 153 de 2012 ))) or ( ley 1530 de 2016 ))*.
